If you’re eating vegetables you are probably pushing unhealthier food out of your diet.

I think we need to think about our physical activity as a reward, as something enjoyable and something we look forward to doing, not something that we regard as self-flogging.

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?

Actually, when you get into your sixties and above, you want to think about exercise differently. It's not just about you know cardiovascular or lifting weights. It's also about avoiding accidents.

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.
