Lhasa Tibet

I just arrived in Lhasa and the altitude hit immediately. No headache, but my brain is working at 1/3 the speed of normal which is saying a lot. The conversation among my two fellow travelers in the car ride to the hotel was something like this:

Wow. It is very pretty here.

Yes. Very pretty.

Yeah.

Is that a cow in the road.

No. A yak.

A yak.

Yeah.

I thought yaks looked different. More hair.

No. In winter maybe more hair.

Oh.

Appetite is light, very lethargic, short of breath. They keep telling us: drink lots of water; don't do much; don't eat much; don't shower tonight. Ok.
