Exercise is good, but is it actually good for you to overstress your heart so much? What if it just quits, what will you do then? (you won't be doing much I'll wager) Is it GOOD for your heart to do this?- I'd really be interested in knowing that- any experts out there?...
Ah now... feeling like throwing up after a good hard run or ride... is invigorating (?spelling?)!

I always love that feeling after I really push it on a run.
