Epigenetics is the study of how behavior, the environment, and other factors can trigger chemical changes to DNA or nearby proteins that affect how genes work. Collectively, these changes (known as epigenetic marks) may provide clues about health and longevity.

Gray divorce—which involves couples ages 50 and older ending their marriage—has become more common over the past 30 years. While divorce increases the odds of mental and physical health problems at any age, older adults face heightened health risks during a stage when many people already have chronic conditions.

The term “longevity” encompasses both living longer and staying in good health. Research consistently indicates that five lifestyle pillars promote longevity: movement, nutrition, sleep, stress reduction, and socialization. But it’s impossible to gauge which pillar counts most toward longevity.

Longevity (or healthspan) specialists focus on preventing age-related disease and extending people’s healthy years, rather than waiting to treat illness once it appears. Ideally, a longevity specialist focuses on proven health fundamentals before supplements and experimental therapies.

A 2026 study suggested that feeling lonely was consistently linked to worsening cognitive health and a shorter life among older adults, even after accounting for social isolation.

There are things our bodies do so often and so automatically that we barely notice them. Yawning, growling stomachs, and runny noses are good examples. Each is a universal part of our daily human experience — but did you ever wonder why?

Falls among older adults are on the rise, but most are preventable. To do this, interventions must target the multiple factors that contribute to falls, taking steps to minimize them or prevent them entirely.

People’s energy levels typically decrease later in life as a result of aging, illness, or other factors. Fortunately, a healthier lifestyle can boost energy. That involves eating a diet low in added sugars and processed foods, getting seven to nine hours of sleep each night, managing stress, getting lots of aerobic exercise, and strengthening the muscles. Using physical energy frugally is another useful strategy. For example, it helps to perform activities at a slow, steady pace instead of a fast pace; to break activities into small tasks instead of one large job; and to rest between tasks.

Many strategies can help people avoid falls in public places. For example, people can wear shoes with nonslip treads in stores and office buildings, use a rollator for stability in crowded areas such as airports or shopping malls, hold handrails on public staircases (or avoid them), avoid parking too close to vehicles in parking lots, or use the handicap stall in public bathrooms. Another important strategy is regularly strengthening leg and core muscles and practicing balance exercises (such as standing on one leg).

A variety of disparate factors can speed up people’s biological aging, which describes how well their body functions (in comparison to chronological aging). Drivers of aging include ultraviolet light, stress, smoking, obesity, radiation, and loneliness and social isolation.
