walking
"Walking is like grounding yourself back to reality getting you mind off a problem for a while and distracting yourself by interactive body experience - It gives your mind quiet time to think subconsciously while your body walks
and then you naturally come up with ideas"
"Walking is like stop-and-go driving," Donelan says. "Within every stride, the muscles are accelerating and then decelerating the body. Hybrid cars take energy and give it to the battery."
"Walking is like medicine for my patients. If walking was a pill or surgical procedure," it would be all over the news, says Dr. Bob Sallis , a family practitioner in Fontana, California. Sallis is just one of many health care providers, researchers and policymakers planning to attend the Summit.
"We're also now acutely aware that running is actually bad for you. It leaves you prone to injuries, and presents the possibility of becoming tired. It's much more dangerous than walking. A good analogy is that running is like shooting heroin, while walking is like smoking a cigarette, which is actually quite good for you assuming that you're walking while doing it."
