Timothy Clagg,

Aging is changing fast. People are living longer, staying active later in life, and demanding more from their health. Whether you’re in your 50s, 60s, 70s, or beyond, science shows that your daily habits have far more impact on your lifespan and healthspan than genetics ever will. Here are 50 powerful statistics you need to know in 2025 about longevity, strength, mobility, nutrition, sleep, and healthy aging.

2025 LONGEVITY & AGING STATISTICS

1. The average life expectancy in the U.S. is 78.9 years in 2025 slightly up from post-pandemic lows.

20. Only 28% of adults over 50 meet weekly exercise recommendations.
21. Metabolism slows 2–5% per decade but can be preserved with strength training.
22. A healthy waist circumference can add up to 6 years to lifespan.
23. Losing just 5–7% of body weight significantly can reduce diabetes risk.

NUTRITION & SUPPLEMENTS

24. Adults over 50 need 20–40% more protein than younger adults to maintain muscle.
25. Only 30% of older adults hit their ideal daily protein intake.
26. Higher protein diets can reduce frailty risk by 30%.

You can’t control how old you are…
But you CAN control how well you age.
