• Social Connections: Strong social relationships contribute to mental and emotional well-being, reducing stress and promoting a sense of purpose.

This report provides a detailed analysis of each of these factors, supported by scientific evidence and expert opinions. It also offers actionable recommendations for individuals seeking to improve their longevity and healthspan.

Introduction

The pursuit of a long and healthy life has been a human aspiration for centuries. While advances in medicine have contributed to increased life expectancy ³, the focus has shifted in recent years to not just living longer, but living better. Healthspan, a concept that emphasizes the quality of life rather than just its duration, has gained prominence. Dr. Peter Attia, a leading expert in the science of longevity, defines lifespan as "essentially your 'expiry date'," indicating how long you will live, while healthspan refers to "the years you live fully—physically, mentally, and emotionally healthy" ¹. This report delves into the science of longevity and healthspan, identifying the most impactful lifestyle changes that individuals can make to maximize their healthy years.

A concerning trend is the widening gap between lifespan and healthspan. Globally, the average healthspan is 9 years shorter than the average lifespan ⁴. In the United States, this gap is even more pronounced, with most Americans experiencing only one healthy birthday after age 65 ⁵. This disparity underscores the need for proactive wellness-centric care systems ² and highlights the importance of focusing on healthspan optimization.

Furthermore, there is a significant gender disparity in the lifespan-healthspan gap, with women experiencing a larger gap than men ². This difference is attributed to various factors, including differences in disease prevalence and healthcare access.

To understand the factors that contribute to health and wellness, this report draws upon the Hartman Group Health and Wellness World Model ⁶. This model provides a framework for understanding how consumers approach health and wellness, taking into account their values, beliefs, and behaviors.

Physical Activity

Regular physical activity is a cornerstone of healthy aging. It has numerous benefits for both physical and mental health, including:

• Reduced Risk of Chronic Diseases: Exercise helps prevent and manage various chronic conditions, such as heart disease, stroke, type 2 diabetes, and certain types of cancer ³.
• Improved Cardiovascular Health: Physical activity strengthens the heart and improves blood circulation, reducing the risk of cardiovascular disease ⁸.
• Weight Management: Exercise helps maintain a healthy weight, which is crucial for preventing obesity-related health problems ⁸.
• Stronger Bones and Muscles: Physical activity helps maintain bone density and muscle mass, reducing the risk of osteoporosis and sarcopenia (age-related muscle loss) ⁵.
• Enhanced Cognitive Function: Exercise improves blood flow to the brain, which can enhance cognitive function and memory ⁸.
• Improved Mental Well-being: Physical activity can reduce stress, anxiety, and symptoms of depression ⁸.

Types of Exercise:

• Aerobic Exercise: Activities such as brisk walking, running, swimming, and cycling improve cardiovascular health and endurance ⁸. Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week ³. You can break this down into smaller chunks throughout the week, such as 30 minutes of brisk walking five days a week.
• Strength Training: Exercises that involve lifting weights or using resistance bands help build and maintain muscle mass ⁵. Incorporate strength training exercises that work all major muscle groups two or more days a week ³. This could include exercises like squats, lunges, push-ups, and rows.
• Flexibility and Balance Exercises: Activities such as yoga and tai chi improve flexibility, balance, and coordination, reducing the risk of falls ⁸. Include these activities regularly in your routine.

Fitness vs. Thinness:

It's important to note that being in shape is more crucial for longevity than being thin ³. This means that focusing on physical fitness and building muscle mass is more important than simply trying to lose weight.

Impact of Inactivity:

Low physical activity has a significant impact on lifespan, with studies showing a 30-45% higher risk of death associated with inactivity ⁷. This highlights the importance of making physical activity a regular part of your lifestyle.

Geroscience Perspective

The geroscience hypothesis posits that aging is a malleable process, and by targeting the hallmarks of biological aging, it is possible to alleviate age-related diseases and dysfunction and extend healthspan ¹⁰. This field aims to prevent the development of multiple disorders with age, thereby extending the period of healthy life.

Several molecular pathways associated with aging are being investigated, including autophagy, cellular senescence, the growth hormone/insulin-like growth factor (GH/IGF) axis, epigenetics, metabolomics, proteomics, DNA damage, and mitochondrial dysfunction ¹⁰.

Cellular and Molecular Mechanisms of Aging

One fundamental aspect of aging is cellular senescence ¹². Senescence is a state in which cells stop dividing but remain metabolically active. While senescent cells can have beneficial roles, such as preventing tumor growth, their accumulation with age can contribute to tissue deterioration, inflammation, and age-related conditions.

Epigenetics and Aging

Epigenetic aging reflects the operating system of the cell, and epigenetic signatures affect cell identity across aging ¹⁰. Studies have shown that accelerated epigenetic aging is associated with increased mortality risk and other age-related outcomes ¹⁰.
