What's the age at which anti-aging interventions are most impactful?

I assume they don't help much when you're young, because you're already healthy as a youth.

Presumably waiting until you're on your deathbed to start high-intensity intervals is not the best idea either.

Supposing a person had a limited budget of "anti-aging firepower" in the form of pills, exercise, etc. -- what age would be most impactful to apply it?

That is way too complex a question to answer here. If you really want to dig into it including exercise, nutrition, sleep, and medications then the new book "Outlive: The Science & Art of Longevity" by Dr. Peter Attia is a pretty good summary of what we currently know.

I wouldn't think of this from a limited budget perspective. Much of what you can do is cheap or free. It doesn't cost anything to go to sleep earlier.
