I'm 65 and recently got back into cycling. 3 months 900 miles now about 17 mph average. Genes are good on my Mom's side. Not so good on my Dad's. I hate traditional medicine as a visit to the doctors is always a pill push. I've been into alternative medicine for decades and, aside from arthtis, my health is great. I do not take one perscription drug and only succome to maybe over the counter pain meds. once in awhile. The culture has been brainwashed. You should see the looks I get from doctors when asked what drugs I'm on and I say none. Sadly this should be the normal and today is the exception.
Today I have more time, more libito, and feel better than most of my middle age years when I was 55 lbs heavier and popping a couple of "scripts" a day. Many folks I associate with are in there mid to late 70's and look better than me and are fun loving active people. The great thing about cycling is, it will help tremendously holding back father time.
