Abstract

The human desire for everlasting youth and well-being has persisted throughout history. In the modern era, advancements in medicine and the emerging field of longevity have brought this age-old aspiration closer to realization. The remarkable increase in global life expectancy from a mere 30 years in 1870 to an impressive 71 years today, is a monumental healthcare achievement over the past century and a half. This achievement carries profound implications for the economy, necessitating a deeper understanding of the aging process and its influence on economic decision-making. Furthermore, it raises concerns regarding the adjustments required in behavior and lifestyle to adapt to extended lifespans while maintaining a high quality of life. The rise in life expectancy has substantial implications for managing chronic health conditions. Low back pain is nearly ubiquitous, and its global disease burden, particularly in high-socioeconomic standard countries, is high.

The youth and longevity business has carved out a niche from the traditional healthcare industry solely concerned with maintaining a high quality of life while managing the aging process. In this chapter, the authors deliver their perspective on the economic decision-making patterns of an aging population, the demographic changes associated with extended lifespans, and the adaptations in retirement planning and utilization of healthcare systems and social welfare programs. Further, the authors reflect on how aging spine patients adjust their behaviors and lifestyles to align with the demands of prolonged lifespans, prompting considerations of the economic consequences of these adjustments. The pursuit of healthy longevity raises questions about productivity, workforce participation, and the financial implications of supporting extended retire-

ment periods. Healthy longevity refers to empowering individuals to lead longer lives while maintaining optimal physical, mental, and emotional well-being. Achieving healthy longevity entails making choices that significantly impact long-term health outcomes. The authors describe how the otherwise healthy low back pain patient over 50 should adopt a healthy lifestyle, including regular exercise, balanced nutrition, and stress management, to promote healthy aging while enhancing the quality of life during extended lifespans.

Keywords: Aging patients, Financial implications, Healthy longevity, Low back pain, Productivity, Workforce participation.

INTRODUCTION

For as long as human history has been documented, pursuing the fountain of youth has remained a steadfast endeavor driven by the desire to achieve an extended and healthier lifespan [1]. Today, fueled by remarkable advances in medical science and the exponential growth of the rejuvenation industry, this ancient dream is gradually becoming a reality. An astounding transformation in global life expectancy is a testament to the remarkable progress achieved over the past 150 years in healthcare. From a meager 30 years in 1870 (Fig. 1), the average lifespan has reached 71 years—an unprecedented milestone [2], leaving a significant health-to-life span gap of 9.2 years [3].

Fig. (1)) Illustration of the health span to lifespan gap of 9.2 years [3].

Several considerations regarding longevity and low back pain are of concern [4]. Firstly, the substantial increase in life expectancy necessitates a deeper understanding of the aging process and its implications for economic decision-making. With a population composed of individuals living longer, it becomes imperative to examine the complex dynamics of aging, low back pain, and its associated effects on various economic factors. Demographic shifts, such as an aging workforce and increased retirement periods, call for adaptations in retirement planning, social welfare systems, and healthcare services. Understanding the economic consequences of managing low back pain during a prolonged lifespan should enable patients, their physicians, policymakers, and economists to devise effective strategies that ensure economic stability and sustainability in the face of evolving demographic patterns [5].

Secondly, growing life expectancy raises pressing concerns about the necessary adjustments in behaviors and lifestyle habits to adapt to these long lifespans while preserving a high quality of life despite the burden of degenerative spine disease, which often manifests as low back and neurogenic claudication symptoms. From a practical point of view, it often means that patients need to reassess their choices and habits to navigate the challenges and opportunities presented by healthier longer lives. Associated factors affecting patients' life planning in their later years include financial and career management and healthcare utilization in the context of their overall well-being [1]. Such considerations are essential in enabling individuals to make informed decisions that optimize their well-being throughout their extended lifespans.

The ultimate goal of healthy longevity is to empower individuals to lead longer lives while maintaining optimal physical, mental, and emotional well-being. The key lies in making proactive and sustainable choices that positively impact long-term health outcomes. Engaging in a healthy lifestyle, encompassing regular exercise, a balanced diet, adequate sleep, stress management, and social connectedness, has been repeatedly shown to contribute to healthy aging and high quality of life significantly [1]. These lifestyle choices are fundamental pillars in the pursuit of healthy longevity, providing a robust foundation for individuals to age gracefully and enjoy enhanced well-being [6].

The authors of this chapter have become increasingly aware of a changing outlook in the healthy well-aging patient population and the need to offer treatments commensurate with the patient's goals and functional status. Low back pain is a significant concern for many of the authors' patients over age 50. These types of patients need to be better served by the spine care models running in public health care systems, where image-based criteria are often the foundation of medical necessity criteria for intervention or surgery. Frustrated, they often seek out the private practitioner for help. Hence, the need for a more structured care model for these highly functional patients - a care model that goes beyond the notion that healthy lifestyle choices profoundly impact long-term health outcomes and that regular physical activity has been linked to reduced risks of chronic conditions such as cardiovascular disease, diabetes, and certain cancers.

In this chapter, the authors examine the importance of mental and emotional well-being by highlighting the interplay between psychological health and physical health outcomes. Cultivating practices that foster mental resilience, emotional intelligence, and social support systems contribute to a holistic approach to healthy longevity and are the cornerstone of many business models that revolve around selling the idea of eternal youth.

Commercialization

Investors, entrepreneurs, and established companies have increasingly recognized the vast potential of the longevity market [7]. They actively invest in driving research, development, and commercialization of cutting-edge products and services. The emergent longevity industry is currently at the forefront of efforts to revolutionize healthcare by devising innovative treatments that target aging and aim to extend a healthy lifespan. This industry encompasses diverse sectors, including biotechnology firms, pharmaceutical companies, supplement manufacturers, longevity clinics, and more [8]. The collaborative efforts of these entities are paving the way for groundbreaking advancements in the field.

Moreover, governments and health systems have begun to acknowledge the significance of healthy aging initiatives, acknowledging the opportunity to mitigate the soaring healthcare costs associated with age-related diseases. The impact of the COVID-19 pandemic has further underscored the importance of implementing preventive health measures and addressing the specific vulnerabilities that arise with advancing age. This realization has prompted policymakers and healthcare systems to prioritize initiatives that promote healthy aging and focus on proactive measures to enhance overall well-being in aging populations.

The convergence of investment, entrepreneurial drive, and governmental support signifies a paradigm shift towards prioritizing and harnessing the potential of healthy aging. By fostering collaboration between private and public sectors, we can anticipate accelerated progress in developing effective interventions, therapies, and preventive strategies that address the challenges posed by aging. This concerted effort holds the promise of extending lifespans and ensuring that those extra years are characterized by vitality and well-being.

Strong future growth of the wellness economy has been predicted by the Global Wellness Institute (GWI) with a post-pandemic resurgence, with an average annual growth rate of 9.9%.

Aging

Aging manifests as a complex process that triggers the progressive functional decline of various tissues and organs. At the molecular, cellular, and physiological levels, aging encompasses many interconnected features, including genome and epigenome alterations, protein homeostasis disruptions, diminished cellular and subcellular functions, and disturbances in immune signaling. As the aging process unfolds, mitochondrial DNA experiences oxidative damage to varying extents, resulting in impaired cellular energy metabolism, cellular dysfunction, and even cell death. The interplay between the antioxidant capacity of mitochondria and age-related changes disrupts physiological cell signaling, compromising cell integrity and hastening aging.

One notable consequence of aging is the emergence of low-grade chronic inflammation, commonly referred to as inflammation. This persistent state of inflammation has been associated with numerous degenerative disorders in human populations. Intriguingly, inflammation induces local tissue inflammation and systemic changes in endocrine, metabolic, and nutritional systems, further exacerbating pro-inflammatory conditions (Fig. 3).

Fig. (3)) Graphic illustration of the relationship between aging and inflammation.

Inflammaging assumes a global perspective as it is a common biological denominator underlying a range of seemingly disparate age-related pathologies, including atherosclerosis, cardiovascular diseases, type 2 diabetes, metabolic syndrome, sarcopenia, osteoporosis, cognitive impairment, and frailty [10]. Its role in developing painful disc degeneration, known as degenerative disc disease (DDD), has been particularly emphasized. While localized inflammation within intervertebral disc (IVD) tissue has been extensively investigated in recent years, emerging evidence suggests that systemic inflammation also contributes to DDD (Fig. 4).

Therefore, interventions targeting the reduction and management of inflammation hold significant promise as powerful tools to modulate and counteract age-related health deterioration, functional decline, and cognitive impairment and ultimately extend the population's lifespan [10]. Researchers and clinicians can unlock novel approaches to enhance overall health and well-being during aging by focusing on strategies that aim to mitigate inflammation.

Degenerative Musculoskeletal Diseases

Degenerative musculoskeletal diseases (DMD), encompassing conditions such as osteoporosis, osteoarthritis, degenerative disc disease, and sarcopenia, pose significant challenges for the aging population. These conditions severely restrict mobility and dexterity, increasing the risk of falls and leading to early retirement, diminished well-being, and reduced social participation. Consequently, they profoundly impact the overall quality of life, causing a significant reduction in well-being [10]. Among these DMDs, intervertebral disc (IVD) degeneration is widely acknowledged as contributing to low back pain. While obesity, genetics, trauma, and sedentary lifestyles have been associated with IVD degeneration, the precise cellular and molecular mechanisms underlying this degeneration are complex and multifactorial.

Fig. (4)) Graphic illustration of the relationship between localized inflammation within intervertebral disc (IVD) tissue and systemic inflammation which may also contribute to degenerative disc disease.

IVD degeneration is a significant driver of low back pain (LBP), with a lifetime prevalence of 84%. LBP is the primary cause of disability worldwide, affecting most adults at some point in their lives. Since 1990, the number of years lost to disability due to LBP has risen by 54% [11]. Managing low back pain is challenging, as it is often classified as non-specific, with the specific source of pain remaining unidentified. Furthermore, LBP frequently coexists with other medical comorbidities, requiring additional attention and resulting in poorer treatment response. The persistence of low back pain is evident, with approximately two-thirds of patients still experiencing pain after twelve months.

A recent study published in The Lancet highlighted the prevalence of low back pain, one of the most common types of pain reported in healthcare settings drawing upon data from the 2021 Global Burden of Disease Study [12]. In a 2023 Lancet publication, the authors estimated the worldwide prevalence of low back pain between 1990 and 2020 across over 204 countries and territories [13]. The findings revealed that in 2020 alone, low back pain affected a staggering 619 million individuals worldwide, with projections indicating a rise to approximately 843 million by 2050, representing a 36.4% rise. In 2020, the global age-standardized rate of years lived with disability (YLDs) was 832 per 100,000 population, ranging from 578 to 1070. Over the period from 1990 to 2020, there was a decrease in the age-standardized rates of both prevalence and YLDs, amounting to 10.4% (with a range of 10.9 to 10.0) and 10.5% (ranging from 11.1 to 10.0) respectively. Notably, 38.8% (with a range of 28.7 to 47.0) of YLDs were attributed to occupational factors, smoking, and high body mass index (BMI) [13]. The most significant increase is expected in Asia and Africa, primarily driven by population growth. However, aging is anticipated to be the main driver in East Asia, South Asia, Latin America, and the Caribbean. The study, published in The Lancet Rheumatology, is part of the Global Burden of Disease Study 2021. The research highlights that older people face a higher risk as the prevalence of low back pain increases with age, with 85 years being the peak age of impact. The high vulnerability of the elderly population highlights the need for specific clinical guidelines for managing low back pain in this group.

Globally, low back pain accounted for 69 million years lived with disability (YLDs) in 2020, indicating the years spent in suboptimal health. Although there has been a decrease in all-cause YLDs since 1990, low back pain remains the primary driver of YLDs worldwide [13]. The Lancet study identifies several risk factors for low back pain, including smoking, obesity, and occupational ergonomic factors such as repetitive movements and heavy lifting at work [13]. These factors contribute to nearly 40% of the YLDs associated with low back pain. The prevalence of low back pain varies across regions, causes, and age groups. The study analyzes data from 1990 to 2020 in 204 countries and territories. Hungary and the Czech Republic have the highest age-standardized rates of low back pain, while Myanmar and the Maldives have the lowest rates. Population growth and aging are key factors influencing the rankings of different countries in the study [13]. Females exhibited higher global prevalence rates than males across all age groups, with more pronounced differences observed in older age groups, particularly among those over 75 (Fig. 5). The global age-standardized prevalence rate per 100,000 was also higher in females (9330; 95% uncertainty interval [UI] 8370–10,500) than in males (5520; 4930–6190). Prevalence and years lived with disability (YLDs) increased with age, reaching peak rates around 85 years. Among all age groups, the 80–84 age group had the highest YLD rate per 100,000 globally (2440; 1470–3490).

The study highlights low back pain's enormous societal and economic impact, including productivity loss due to missed workdays and reliance on pain medication and emphasizes the need for public health prevention strategies, particularly for the elderly, and notes that low back pain leads to more people leaving the workforce than any other chronic health condition among working-age populations. Further, research consistently demonstrates a strong correlation between back pain and reduced physical activity [14]. The limitations imposed by back pain often result in a sedentary lifestyle, as individuals avoid movements that exacerbate their discomfort. However, this lack of physical activity can harm overall health, including weight gain, muscle weakness, cardiovascular problems, and an increased risk of chronic conditions such as diabetes and heart disease [14]. Addressing the challenges associated with DMDs and low back pain requires comprehensive approaches that encompass early detection, effective treatment strategies, and a focus on promoting physical activity and overall well-being. By prioritizing research, prevention, and targeted interventions, we can strive to alleviate the burden imposed by these conditions and enhance the quality of life for individuals affected.

Precision Medicine

The emerging paradigm of precision medicine holds immense potential to revolutionize healthcare by customizing interventions to individual needs, ultimately leading to improved patient outcomes and optimized resource utilization. This transformative approach aims to provide more accurate diagnoses, effective treatments, and targeted preventive strategies, resulting in enhanced health outcomes and a higher quality of life for individuals. In low back pain, advancements in diagnostic tools are being harnessed to identify underlying causes and contributing factors, thereby guiding appropriate treatment and prevention strategies. Significant progress has been made in diagnostic imaging technologies, such as magnetic resonance imaging (MRI) [15-20], positron emission tomography (PET) [21], and computed tomography (CT) [22]. These state-of-the-art imaging modalities have undergone significant advancements in resolution and diagnostic capabilities. By offering detailed anatomical and functional information, they play a pivotal role in detecting, staging, and following various diseases and conditions.

By leveraging these advanced diagnostic tools, individuals can adopt a proactive approach to their health. Armed with comprehensive information, they can make informed decisions and embrace preventive strategies to maintain optimal wellness and reduce the risk of developing certain diseases or conditions. Precision medicine empowers individuals to understand their unique health profiles and tailor interventions accordingly, promoting early detection, personalized treatment plans, and targeted preventive measures. This individualized approach to healthcare has far-reaching implications [23]. It enables healthcare providers to optimize treatment outcomes by tailoring interventions to each patient's needs, reducing the risk of adverse effects and minimizing healthcare costs associated with trial-and-error approaches [23]. Additionally, precision medicine supports proactive health management, shifting the focus from reactive care to preventive strategies. By identifying risk factors, genetic predispositions, and early disease indicators, interventions can be initiated before symptoms manifest, potentially mitigating the impact of diseases and improving long-term health outcomes.

Precision medicine in pain management and spine care holds the promise for developing novel therapeutics and interventions thereby decreasing the need for opioids. By understanding the intricate molecular and genetic mechanisms underlying pain syndromes, clinicians involved in interventional and surgical pain management can identify specific targets for intervention and design tailored treatments of pain generators that are more effective and potentially less invasive and costly (Fig. 6).

Targeted Care Models

As precision medicine continues to evolve, it has the potential to revolutionize healthcare systems, enhancing patient care and fostering a more personalized and proactive approach to well-being. The latter is relevant to aging but a healthy patient who is held back by low back pain-related problems that ultimately impact the physical and emotional outlook on life. By integrating advanced diagnostic tools, genetic profiling, and targeted interventions, targeted precision medicine represents a significant stride toward improving healthcare outcomes and promoting individualized wellness. Many of the chapters are on novel targeted care models based on the improved understanding of the molecular and genetic mechanism of painful conditions affecting the musculoskeletal system and the spine in particular. Patients will increasingly gravitate towards practitioners who address their individual concerns and offer alternatives to the stalemate frequently playing out in public health care systems where red tape and bureaucracy are directing care employing population-based health care models. These systems will likely prove unsustainable because of constant cost overruns, and rationing – nowadays already seen in many healthcare systems - would be the only way to control cost [24-26]. Here lies the opportunity for those businesses to address the increasingly unmet needs of patients left without help by the traditional care models (Fig. 7).

CONCLUSION

The health longevity market is expected to grow as the world's population ages, and people continue to adopt healthy lifestyles to promote longevity. This includes regular exercise, stress management techniques, sleep optimization, and healthy eating. The marketplace offers various services, products, and experiences intended to support these lifestyle choices. As the quest for eternal youth continues, it is essential to maintain a realistic perspective and focus on promoting healthy lifestyles, preventative care, and advances in medical science. These approaches can significantly improve the quality of life, extend healthy years, and support the overall goal of aging gracefully and maintaining well-being as we age. The intersection of regenerative medicine, stem cells, and intervertebral disc regeneration presents a unique opportunity to promote healthy longevity. By harnessing the regenerative potential of stem cells, clinician-researchers are paving the way for innovative therapies that can restore damaged intervertebral discs, relieve back pain, and improve mobility. The potential preventative effects of these therapies offer the potential to maintain spinal health as people age, contributing to a longer, healthier life with a better quality of life.
