Too much exercise is not a good thing

Sawadee Khrap

Got’ta slow down – limit my exercise program !
Ya know, when I was 25 and got a hard-on, I couldn’t bend it  with both hands.  At 50, I could bend it about 20 degrees if I tried real hard and by the time I reached 60, I could bend it 45 degrees, no problem.

I just turned 75 and I can bend it in half with just one hand.
How much stronger am I going to get?
