Exercise!
Well, when your reputation is staked on being able to find the good and learning from everything, you can't just start becoming a victim of either your aging body or any beliefs about what aging means. So my adventure here on Planet Earth at age 70 is like this and this is what I'm learning:
An aging body will sure teach you to take care of your body. The results of not doing it can be felt almost immediately. I pretty much got through my life doing a very minimum of exercise still looking OK and being able to move rather automatically.
Can't get away with that any more. It doesn't matter whether I have issues and want to take my time getting over this, it will not cooperate. If I don't exercise frequently - like daily - I feel not great in my body and my balance and strength dwindles perceptibly even though I eat very, very healthy and have done so for years.
OK. I WILL LOVE MYSELF ENOUGH TO TAKE COMPLETE CARE OF MY BODY. NO EXCUSES!
