As we get older and most of us become more sedentary in our lives, (sitting too much at work, long commutes, air travel etc.) our muscles become ever increasingly tight. 

Incorporating more daily stretching has been a New Years resolution of mine for years. Eventually it becomes part of a daily routine.

Stretching, even a just a few minutes a day, can be very beneficial. Give it a try.

(P.S. This goes for your muscles and your mind)
