The benefits of exercise extend far beyond physical health improvement. Many people work out as much for mental and spiritual well-being as for staying fit. Can being physically active make you happy? Can it help you deal with life stress? Can it lead to a more spiritual and religious life? For many, the answer is yes. Exercise, such as walking, increases blood flow to the brain. A study of people over 60 found that walking 45 minutes a day at 6 km/h enhanced the participants' thinking skills. They started at 15 minutes of walking and gradually increased exercise time and speed. The result was that the participants were found mentally sharper with this walking program.
