Following retirement 15 years ago, I created an exercise plan to keep me healthy until age 85 if possible.
First, I had cataracts removed in both eyes. Now I can read the newspaper without glasses!
Next I bought an exercise bike. My plan lets me exercise one half-hour daily with variations for weather. I bike for 15 minutes. In bad weather I bike for 30 minutes.
Now I’m 85 years old but can walk as easily as when only 70, so I’ll continue.
