Walker or Walker?

My wife is amazing! Simply amazing! Check out her blog! She is doing a 5 mile walk to raise money for the American Heart Association less than 7 weeks after major surgery. Let me be candid, if I am less than seven weeks out of that kind of surgery (of course there would have be a lot of surgery prior to me having the same surgery that Kim had) I'm not a Heart Association walker - I'm still using a walker.
