The world of supplements and "anti-aging" practitioners is unfortunately riddled with misleading claims, dubious advertising, and vigorously promoted treatments of no proven benefit. I find this quite frustrating for two reasons: first, because patients who spend a lot of money on ineffective treatments become discouraged and disillusioned, and we lose the opportunity to help them; and second, because it makes all of us in Age Management Medicine look bad—and most of us are trying to do the right thing for our patients.

Hippocrates is often referred to as the "Father of (Western) medicine", and is relentlessly quoted for having said "First, do no harm." Good advice, to be sure! But I'm drawn to a lesser-known quote of his:

"There are, in effect, two things: to know, and to believe one knows. To know is science. To believe one knows is ignorance.""
