There's also a fascinating tension with physical exercise, which is that your preference would obviously be do it as early as possible, so you spend more time at a younger age as opposed to just prolonging the last years of your life, where you'll be stuck in a nursing home anyway.

But doing exercise while you're young is also much higher risk, and you might see people sacrificing their 20s for the sake of their 70s in a way they end up regretting, even if there aren't any injuries.

That said, even with risk of injuries it feels like a no brainer to be active and to be active from an early age.

Also I don’t think people should wait until their late 50ies to make sure they get enough vitamin c to “avoid sacrificing their 20ies”
