A high VO2 max is a factor that enables individuals to be sexually active in the last decade of their life.

“Seven mets translates to about a V2 of 25 milliliters per kilogram per minute. Which means if you want to be able to have sex in your marginal decade, you need to have a V2 max of probably about 30 milliliters per kilogram per minute. [...] And while most adults can easily muster a V2 max of 30 milliliters per kilogram per minute, if you want to be able to achieve that in your 80s or 90s when you're my age or your age, you're a lot younger than me, you need to be probably north of 45 or 50.”
