Yes, I feel like I've been hit by a truck. The elevation here means the air is so thin I can't sleep even when insomnia isn't tormenting me. I fall asleep for a few minutes and then wake up suffocating. I force myself to get three deep breaths and then sit up and get nervous. I would normally go to the fridge for something sweet, but I can't find an appetite here. That makes it all the harder to walk around and do things of interest-- or anything at all. I am totally worn out from this, and I have yet to go across Lake Titicaca to make my way to Bolivia. But I will somehow keep on going. As hard as this sometimes is I don't want to turn back till I do whatever I can do. A boat ride on the lake is just the thing for me, I think. And if I survive it, on to La Pas, south from there to the place Che was shot to death, and maybe a detour into the souther Altiplano to visit the reputed place where Butch Cassidy and Sundance Kid were shot. If any of that doesn't kill me, then I will attempt some further travel, down to Paraguay, described in an unforgettable headline in Rolling Stone Magazine about 40 years ago as "The Last Place on Earth for the Worst People in the World."
It's the high life for this guy. Tomorrow, assuming I have the strength, I'll report somewhat on my away trip to see a pre-Inca burial site outside of Puno. It was all that I had hoped to have at Machu Piccu. Had a good time on an away trip with a bus load of others.
But it has to wait till tomorrow. This evening, I'm beat.
