The claimWhat Jane actually said

In a 2025 Hollywood Reporter feature, Fonda said that unless you want to end up in a wheelchair, dependent on others, you have to stay strong, and that staying fit and flexible is far more important when you are older than when you are young.

Why it mattersWhy this matters for longevity

Mobility, balance, and strength quietly decline with age, and they strongly predict whether people keep their independence.

Regular movement supports the heart, mood, bone density, and the everyday confidence to keep doing the things that make life full.

The evidenceWhat the science says

A dose-response meta-analysis of 80 cohort studies, more than 1.3 million people, found higher physical activity is associated with lower all-cause mortality across every domain of activity.

A separate dose-response meta-analysis of step counts found mortality keeps falling as daily steps rise, reinforcing that staying active, not elite training, is what moves the needle.

The honest caveat: this evidence is observational. It shows a strong, consistent link, not proof, and it improves the odds rather than guaranteeing them.

The practical lesson

Choose movement you enjoy enough to repeat, add a little balance and strength work, and adjust rather than quit when your body changes. The win is the streak, not any single session.
