There isn't one now, fine. But why shouldn't we be trying to invent one?

  You're welcome to try. If you succeed even partially then you'll be a billionaire. But these are complex biological systems and it's a tremendously difficult problem. I guarantee you that within our lifetimes we won't see a safe and effective drug that produces health benefits equivalent to frequent hard exercise. Many of those benefits come from the physical motion which helps to keep blood and lymph circulating normally so I can't see any way to put that in a pill.
