Introduction

This episode, we're going to be talking about aging. Why exactly do we age? What's happening at the cellular level as our bodies get older? Scientists are still chasing many of the answers, but there have been some important advances in understanding the distinctive changes we call aging. We'll ask, what role do our jeans play in aging? And why do women tend to live longer than men on average? Also, what is research finding out about the ways we might slow down the process of aging? Later in this episode, we'll hear from doctor dena duball, associate professor in the department of neurology at the university of california san francisco.
