I have a few clarifications to Matt’s post. #1.) My daily activity consisted of more than just walking for 20 minutes, so he speaks for himself there. #2.) I wouldn’t say I was “plagued” by knee problems the last two years, but it did start bothering me significantly more during this trip.  However, during a certain bathroom break at the airport my knee popped so loudly that I thought I might be stuck in the squatting position permanently.  Fortunately this was not the case, and I think the pop relieved some of the problems in my knee, resulting in no problems with it during the trek and thereafter.  #3.) We walked often before the trek.  I don’t think this has changed much.  It’s cheaper that way, duh.   #4.) After a few days of 3-4 hours straight of stairs during the trek, I will say that a small hill of stairs leading up to a temple or cave is much less intimidating than before.  #5.)  That cave was freaky and the spider as big as my face.  Ok, maybe not as big as my face because I have a big head, but it was definitely large enough to cover the average person’s face…  #6.) Yes, I was definitely pedaling faster than Matt.
