“You can open up a centenarian's brain, and you'll see some areas that look like …” — S. Jay Olshansky

Humans will die like all living things do, but we have the added burden of knowing that we will.

A lot of people are living in a dream world - they want to deny that aging occurs or believe it doesn't have to occur. They'll hold on to this belief until the moment they die. The reality will eventually hit them.

As soon as a handful of scientists come up with an intervention shown to influence aging in other species, they begin selling it as an intervention for humans, even though there may not be evidence it works.

In Hollywood they're getting younger, but believe me, it's not the food. It's the plastic surgery.
