I have found that a good stretch every morning keeps me in pretty good form. I read an article when I was about 35, it was about people with a high quality of life in their golden years. There were a ton of differences in all of the peoples lives, but the one thing that they all had in common was some sort of fitness routine. Tia Bo, Ti Chi, martial arts, yoga, low impact sports, that and being old 2as all they had in common. That’s when I started with yoga ish exercises. True yoga is different from what I do , but I feel it makes a large impact on my body.
