The median lifespan for a U.S. male is 74 years old.

0:00Three out of 10,000 people live to 100. Everyone has this assumption in their mind that they're like, "Yeah, yeah, I'm at 50, so I'm going to make it to 100." Yeah, well, you've got a three in 10,000 shot at doing that. Very unlikely. More realistically, you'll die at the median, which is 74 for men in the US, which means that at 37, you're actually at the halfway point, just in years. But if you adjust for the increase in speed of time, so the same reason that your kid at 5 years old thinks that something takes [music] forever when you say it's going to happen next year, and when you're 40, something that happens next year feels like you blink your [music] eyes and it's there, is that when you're five, one year is 20% of your life. When you're 40, one year is 2 and 1/2% of your life. And so [music] it very much in real way is nine times faster than it is for your 5-year-old. And so if you adjust for that time speed, your midpoint isn't 37. It's closer to 21.
