Life expectancy in America is about 79, we should be able to live to 92. Somewhere along the line, we're leaving 13 years on the table. So my quest is -- how do we get those extra 13 years? And how do we make those extra 13 years good years?
Exercise, from a public health perspective, is an unmitigated failure. The world's longest-lived people live in environments that nudge them into more movement. They don't use power tools, they do their own yard work, they grow a garden.
The beauty of moving naturally, i.e. walking and gardening, is they're low impact. You're less likely to fall down and break a hip. Setting up your life so you're nudged into general physical activity every day is a strategy for your entire life from age 10 to 100.
