You're going to think I'm crazy and what I say will be different from anyone else's response, but I believe it's the truth. The way our bodies were designed, running (other than for an activity or game) is an indication that we are fleeing from danger. Cortisol is released from the brain and over a period of time damages the heart muscle. Expecting injury, the body wants to minimize bleeding, so the blood vessels constrict and blood pressure rises. The "runners high" is designed to minimize the agony of being killed. Think about it--why have runners in "excellent condition" like Jim Fixx dropped dead? Running any more than for short spurts is no more natural to us than eating bread. Everything you're already doing is just fine--don't ruin it.
I read about this in the book, Lights Out--Sleep, Sugar and Survival by TS Wiley, an anthropologist, in which she also discusses the need to get adequate sleep and why artificial lighting has also contributed to illness. The facts discussed in this book, I believe, are totally consistent with the paleo lifestyle and fill in many of the missing pieces of the puzzle.
