Aging is something that most of us would like to deny. But really, it’s not growing old that kills us. Instead, it’s usually one of many “lifestyle” diseases such as certain types of cancers, Type II diabetes, heart disease and stroke.

So what happens to our bodies as we age, and what can we do to turn back the clock?
