Hello everyone! Today I'm speaking with Physician Bongevity Expert and now author Dr. Peter

Adia. We discuss his new book Outlive, The Science and Art of Bongevity, and explore

the immense benefits that can be gained from exercise in just three hours a week. How small

imbalances in diet can cause major problems such as diabetes and obesity, the difference

between lifespan and health span, the sourd reasoning behind the American food pyramid,

and the scientific side of alternative diets. No buzzwords. Looking forward to the discussion

today. Dr. Adia in your book, you talk about lifespan in general, but you also concentrate

on a concept called health span, termed health span, and you're concentrating more on decades,

let's say, of healthy life rather than absolute length of life. Do you want to expand on the concept

of health span and why you distinguish between that and longevity per se? Yeah, longevity

is really a function of lifespan and health span, so life span is the easier of those two

to understand because it's binary, you're either alive or you're dead, and I think when most

people think of longevity, they think of the elongation of lifespan understandably. But

that's really only part of it. The other part, the part that might actually be more important

to most people when pressed on the issue is health span, which is the quality of life.

Medical definition of health span is not a particularly helpful definition in my view.

It's effectively the period of time from which you are free of disability and disease, but

I don't really think that captures what health span is to most people. And so I think health

span is a broader concept, and it's not binary, it is analog, but it really constitutes some

measure of cognitive health, physical health, and emotional health. And at least two of those

are intimately linked to age, which is to say they generally decline with age. But if

we focus, I think, relentlessly on the pursuit of those things, we tend to get a better quality
