Exercise is our companion in times of need. For many, running is a time in which the legs do the thinking and the mind is free to wander.

The “runner’s high” is one of the many addicting reasons runner’s find themselves craving and yearning to run again and again, always in search for the final moments when their physical exertion meets the sensation of relaxation and success.
