You: Staying Young: The Owner's Manual For Extending Your Warranty

Dear Amazon Shoppers:

Our books, YOU: The Owner's Manual and YOU: On a Diet, have become #1 Amazon and New York Times bestsellers, and we thank you. Many people have asked us questions about aging. We want you to know that the science in the last very few years has challenged the very perceptions of aging.

Most of us tend to have the same view of the way people age: As we grow older, we start losing things. We lose some hair, lose our minds, lose our balance, lose our eyesight, lose a little of this and a lot of that until we eventually wither away into a hunched-over senior who takes 3-inch steps and eats dinner at 4:00 pm. But to think that a life of frailty is an inevitable outcome of aging is a mistake. And the fact that we don't take control of it is because we have excuses. We live in a society where making excuses is as easy as making a sandwich. Nowhere is that more apparent than when it comes to your own health. The reason why we are frazzled with stress? Blame the boss. The reason why we are sick? Blame the sniffling kids. The reason why our society's waistbands are stretching and snapping at alarming rates? Blame Auntie's alfredo sauce. The top health excuse, however, revolves around the biggest four-letter word of them all, the GENE. We blame our genes for just about everything--for baldness, for fatness, for illness and for every other health-related problem we can think of. In our minds, that means that our mom, pop, and the rest of the family tree are all on the hook for the ultimate health question of them all--how long and how well we will live?

But that is exactly where more of us have it wrong. While we are certainly born with genes that help determine everything from our height to our risk of heart disease, we are making a monumental mistake by assuming that we can't control our genes--especially when it comes to aging.

Perhaps the best way to explain the dynamics of aging is to take a look at another complex system that is subjected to the same forces as your body: a city. Some cities remain beautiful and elegant in their old age, while younger ones may look worn down and beat-up. Now, every city has its own genetic code, just as you do. For a city, genes are geography; whether it's built on a river or whether it's located in a hot or cold climate, or whether it lies directly in a prevalent hurricane path. A city's geography can't change. But the city can adapt to the environment with earthquake-proof construction, with underground tunnels for walking in wintertime, or with strong levies. The adaptation the city makes to survive and to thrive is what is crucial to its vitality.

The same goes for you.

Just because you have been dealt a genetic hand that predisposes you to heart disease or diabetes or the wearing of pants as large as a parachute doesn't mean you can't mitigate the effects of those genes. One of the major things we will teach you is that while you can't change your genes, you can change whether they are turned on or off or how you express them. Just like a city, you can compensate elegantly if you understand your options.

For the first time in history, the medical world has uncovered many of the miraculous biologic processes that control how and why we age. Truth is, much of aging is actually in our control; with the power to nudge our biologic systems so that our unwanted genes can work in our favor--as long as you know what to do and how you are doing it. In YOU: Staying Young, we translate the latest science (much of which wasn't available even three years ago) to help slow your rate of aging. You will learn 14 Major Agers, and dozens of action steps so that you can take control of those agers and your aging processes.

We hope you enjoy the cartoons, analogies, and jokes. But ultimately we hope you soak in the message: Your health is largely in your control. We dedicate the book to all who desire longer life so they can serve more.

Thanks very much,

Mike and Mehmet
