6. Walking fast

Researchers of Harvard University found that exercise is one way to slow the aging process. For middle aged women, walking for 45 minutes an hour a day was linked to a 40 percent lower risk of stroke.

A long-term survey conducted by University of Pittsburgh in the U.S. shows that when people walk the volume of gray matter in their forebrain, hindbrain and hippocampus get larger which is linked to a lower risk of cognitive disorders.
