I was wondering the other day while watching some people ruing through 
brush and trees on the show ManTracker, if there was any benefit to 
being whacked by a lot of bushes and small tree branches.  Perhaps an 
immune stimulating effect?  Running through the thick and thin of things 
while chasing food or being chased might have produced this effect 
regularly.

I've always assumed that modern man has higher iron levels since Paleo 
man probably lost a lot more blood from cuts, scrapes, parasites, 
hunting injuries, etc so that giving blood might be a good thing since 
it would lower iron levels (higher iron helps infectious bacteria to 
reproduced) and force replacement of blood cells with more youthful 
ones. Stimulating the skin from hunting/running might be something we 
adapted too also benefit from.
