Secientists still don't fully understand the relationship between exercise and brain power.For the moment,people just have to trust that exercise is helping them to learn or remember.Scientific research clearly shoes,however,that three or more workouts a week are good for you.A study in the Journal of the American Medical Association,for example,shows that walking four to fivemiles(6.5 to 8 km)an hour for 45 minutes five times a weel helps you live longer.So don't be a couch potato.Get out there and do something!
