see, i have this theory about stairs. almost all my classes are on the third level of different buildings at school, so when i first started, i would get winded going up 3 levels...but now, i don't get winded anymore. So my theory is, that i'm building up my muscles...soon i'll be able to run the nyc marathon.
Most of my classes don't require stairs..but there's this hill I walk up at least twice a day now. I still get all disgruntled about it, but eventually I think it will improve my health.
