Charles Eugster may be 93, but he has no less spring in his step than he did as a young man. In this talk from TEDxZurich, he brings us a powerful statistic: 92% of Americans over the age of 65 have one or more chronic diseases. While many clearly cannot be avoided, Eugster points out that inactivity is to blame for many of the diseases those who have lived long lives endure.

During the golden years, people retire and tend to slow down  — and yet there is a connection between work and one’s physical and mental health. But life doesn’t need to finish after retirement, which Eugster calls “voluntary or involuntary unemployment for up to 30 years.” That’s why Eugster has taken up rowing. And weightlifting. Watch this TEDxTalk about the factors for successful aging from a formidable speaker, who urges us to “break off the shackles of convention!”
