Yes Leon i feel it. I am only 41 but have a bad knee from slo-pitch and a bad back at times. Last year i worked out 6 days a week for 45 min a day, quit drinking and ate a healthy diet(lol). I lost 37 lbs in less than 4 months. Sadly i have not been able to keep up the workouts and gained 75% of it back.
Depending on one's situation, i think that people need to feel healthy in their mind to enjoy life.
