Doesn’t mean I should. It was fun to run a little, but we’ve discovered the downside of strenuous exercise: extended background annoying chest discomfort. Angina. If I exercise hard, I have to deal with angina for days. I can take nitroglycerine to open things up (the doctor suggested that) and moderate the chest pains, but then I still have some leftover discomfort, and I also have the nitro head-rush for several hours too. I think I’ll just keep my exercise at an easy walking pace and stay comfortable.
