I think it may not matter so much what you do as long as you do it regularly. I'm a night owl and walking at 6am is about as likely to happen as flying to the moon. But I can walk and cycle at the gym any time and lift weights. I can do yoga. I can commit to a gym membership so I don't backslide. I can walk as much as possible during the day. I can stop 80 hour weeks (in my late 60s) and go to 4 days a week without wrecking myself financially. I can stop talking about joining a choir or taking philosophy classes and do it. Mens sana is as important to me as corpore sano! I didn't do this so much to avoid cancer (be wonderful if it did) but to make the most of my life. We none of us know how long our lives may be and cancer is a powerful reminder that it may not last for ever.
