Exercise also prevents obesity and reduces the energy intake: energy
stored ration. Dietary restriction is known to retard ageing: maybe
there's a link?
Incidentally, although free radicals are commonly portrayed as villains
they actually play important roles as second messengers at very low
concentrations. H2O2 is now known to be a co-factor in the sperm acrosome
reaction even though at high concentrations it's extremely toxic. NO, CO
are also important. Damage comes when free radicals spin out of control.
