Live shortening effects of sport

I had wondered about this. After all, if you "exercise" a car you wear it 

Exercise with animals obviously has two factors:
1. It programs muscle building and other beneficial effects
2. It wears out mechanical parts

In young people 1 outweighs 2.

I suggest as a useful line of research for biochemists that they find out 
the mechanism by which exercise builds muscle and other improving factors, 
and find a nutritional way of replicating this with no side effects.

After all, excercise must by itself be damaging, that is clear. But the 
body rteceives the information that this damage is taking place and 
corrects it, indeed overcorrects it in some aspects by strengthening muscle 
and bone. The actual strengthening of muscle and bone are chemical not 
mechanical processes, and they are initiated by the *information* that 
excercise is taking place. If we can fool the body into beleiving that 
excercise is taking place when it isn't, then we have the benefits without 
the mechanical wear. 

Of course people will still take excercise beacue they like what they are 
doing, eg sports and recreations, but the won't waste their time jumping on 
the spot etc (and wearing out their joints) just to tone themselves up for 
their sports.
