It turns out that hiking in high altitude actually does expand your capacity. I know, shocking news, isn't it? In a strange twist of fate that had most everyone I know gaping at me, I left the car at home and walked to work. In the end it only took ten minutes longer than driving, because driving involves three sets of traffic lights (or more precisely two sets of traffic lights, one of them twice) and hunting for a park and walking back, all of which makes it a highly inefficient process. Except when raining. I strongly suspect my new-found athleticism will not extend to rainy days, and not just because I cannot arrive at work looking like a drowned rat.
In other news, I am already planning my next trip OS (I'm told by reliable, if not always reputable, sources it's the only real cure for post-travel funk). So far I'm thinking the Inca Trail, but Mongolia is high on the list as well. What say you?
If money were no object, what would be at the top of your list?
