Never Underestimate The Power of Working-Out!
Jack LaLanne is the Godfather of Fitness. He died at the age of 96. I love this commercial Cher did, to promote his gym franchises' in the 80's.
There is working-out, and then there is REALLY WORKING-OUT!
Most people fall in the former rather than the latter. I have been really working out for 35 years. Now, that I am older it doesn't really surprise me, the average life expectancy is only around 78. If more people really worked out, it would definitely help the sick care system.
