Anti-Aging Expert (Peter Attia): Anti-aging Cure No One Talks About! 50% Chance Youll Die In A Year If This Happens! Boost Testosterone Naturally Without TRT!

We don't have a single metric of humans that we can measure that better predicts how long they will live than how high their VO2 max is.

At the population level, the best answer as to why testosterone levels are declining... I believe that the best answer probably has to do with two things. One is increase in body weight and fat, body fat, specifically in men and some combination of reduced quality of sleep and sort of disruption to sleep.

Once you reach the age of 65, your mortality from a fall that results in a broken hip or femur is 15 to 30% .. There's a 15-30% chance you'll be dead within a year.

Our healthspan is basically a glider, but we have a lot of control about how long it stays in the air based on how high we can start it.

They took healthy subjects, young subjects, and sleep-deprived them for somewhere between 10 and 14 days ... And they only let them sleep four hours a night .. In that 10 to 14 day period of time, their insulin resistance was worsened by 50%.

Death is inevitable, despite what some biohackers may tell. Decline is inevitable. But the rate of decline is very much up to us; and the preservation of strength, stamina, movement capacity—those things are largely up to us.

No one in the final decade of their life ever said, 'I wish I had less strength, and I wish I wish I had less endurance.' So you cannot be too strong, and you cannot be too fit.

Muscle mass is probably the second most highly correlated finding, or third most, to longevity after strength and cardiorespiratory fitness.

If you take a 35-year-old man and one of them has a VO2 max of 53 and the other one has a VO2 max of 35, there is a 400% difference in their all-cause mortality over the coming year.

It turned out that in the people who were exercising, there was very little decline in the mitochondrial function compared to what happened in the people who were not exercising.

When you sleep-deprive people, they become insulin resistant. And the more insulin resistant a person is, the less they're able to access their stored energy.

There is no evidence that intermittent fasting produces any benefits above the equivalent amount of caloric restriction.
