I liked the running myths debunked article, I have always felt road running easier than trails, especially with no shoes. You can't see what is in the grass. I think running is fun, but I do see long faces on some runners when I am out on a Sunday. I find it really good stress relief after a long day at work.
Running can kill you. Many runners are known to drop dead on the spot while running. Happened here in my city a few years ago. Young man, never smoked, tofu junkie type. Gone in a flash -- heart attack while running.
