Life expectancy for Americans reached a record high of 79 years in 2024. One hundred years ago, the average lifespan was just 63 years. That increase is largely due to improvements in healthcare, sanitation, chronic disease management, and reduced smoking rates. But while we’re clearly living longer — are we living better?
As a physical therapist for 30 years, I’ve been preaching the importance of exercise and nutrition to whoever will listen. Most people don’t truly grasp its importance until it’s too late. My patients over 65 are the most receptive to my “health sermons” because they’re watching friends and family struggle. We tend to blame genetics — but research suggests genetics account for only about 20% of the picture. Studies consistently show that people who stay active, maintain a healthy weight, and live with purpose genuinely thrive in their later years.
Our goal should be a long healthspan — the period of healthy, active life — not just a long lifespan. We want to thrive in our 70s and 80s, not just sit watching Gunsmoke.
