Hi there! Yes, it's hard to adjust to being so fragile physically. Unfortunately in my case it's been an instance of trial-and-error. I so love exercise and i have the means, motive and opportunity. It's just the spirit is willing, but the flesh is weak. I'm really going to have to be cautious and like you say, live to exercise another day.
Edit: I think it's you that doesn't like to be @_mentioned? I initially forgot but edited my post so you might have gotten a notice anyways. Sorry about that. It's been a while since i've 'seen' you.
