Why We Age and How Our Bodies Change

You noticed the first gray hairs a while ago, and lately the menu at the restaurant has started to blur. You are not looking for a fix. You just want to know what is actually going on in there.

This audiobook explains the science of aging one idea at a time, in a calm voice made for a commute. You will hear why hair loses its color and why reading glasses tend to arrive in your forties. A cell that stops dividing gets its own chapter, as do the animals that barely age at all. Along the way you learn what biologists have worked out about why we grow old, and where they honestly still have no answer. Every big number comes with an everyday comparison, and each chapter closes with a short spoken recap so the idea stays with you after you park the car.

By the last chapter, your own body will make more sense, and getting older will feel far less like a mystery. Press play and let the wonder do the work.
