I was planning a trip to Nepal, to hike to Base Camp - Macchu Picchu was a great experience, so I thought this would be the same.

But then a friend send me this:

Apparently, hiking at altitude causes permanent changes in the brain, even at "low" altitudes like EBC - which has kinda freaked me off about the trek.

I wonder how the sherpas/local populace deal with that?
