hi there
i know about feeling overwhelmed..... sigh....
my foot/feet are ok. the problem was with both but the left was worse because i fell on it twice - once after a couple rounds of therapy... haha start over!
i bet the nervous-looking walkers probably were nervous and probably burned off a lot that way

and/or did a lot more walking than just at the park, whereas at least some of the runners probably only did that. running puts me in a mental state that i can't get walking - pls don't suggest speedwalking i couldn't do that i'd feel really awkward.
but what is NAC - the only references i find are N-acetylcysteine (a mucolytic) ... is there also some kind of exercise called that?
love
