II. HOW TO STAY YOUNG
AG: If you were the emperors of the world and had the power to command the populace to do or take three things to counter aging, what would you command?
JK: You do need exercise every day, both for cardiovasular health and to keep your arteries nice and flexible. And you also need strength training, because we're so sedentary. And balance training. That's why we do tai chi in our practice. I had a grandmother who lived to be 95 years old. She ran a farm, did heavy housework every day. If we needed a chicken, she'd go out and kill the chicken, pluck it, and cook it that night. She was a perpetual movement machine. While genetics are responsible for 40 percet of aging, epigenetic studies have shown that the majority of aging is due to lifestyle factors within our control. Most important is the effect of aging on the brain. Age 40 marks the onset of decline in areas of memory and learning. But by learning something new in middle age, we encourage brain growth and stop brain decline. Things like traveling to a new place, learning a new language, or taking a continuing education class are not only enjoyable, they actually keep the brain young. The message here is: This is not your mother's aging. Be proactive! Tackling age is more than cosmetic makeover: it's building a foundation of health.
III. WHEN DOES OLD BEGIN?
AG: How does a patient know when she's going too far with cosmetic surgery ?
JK: Some don't. And it looks a little awful. Isn't there a certain beauty to aging? To the natural aging process? In Europe it's much more that way.
IV. IS AGE A DISEASE?
JK: It comes down to epigenetics - how your diet effects your DNA. There's a sameness to young brains, and there's a sameness to old brains. But there's a big window in between, from 40 to 70 years old, where some brains look like old brains and some brains look like young brains. There are things we can do to keep our brains young and healthy, like following the Mediterranean diet.
