Exercise

 

"We are under exercised as a nation. We look instead of play. We ride instead of walk. Our existence deprives us of the minimum of physical activity essential for healthy living."  ~ John F. Kennedy

"Walking is the best possible exercise. Habituate yourself to walk very fast."  ~ Thomas Jefferson

 “The sovereign invigorator of the body is exercise, and of all exercises walking is the best.”

~ Thomas Jefferson
