I'm smart enough to know I could not walk up to the Jesus statue while my brain is pounding out of my head like a bass drum.
I spent two hours in the Plaza de Armas, people watching next to a woman with traditional dress... then I fell asleep next to her. Beside me was the cathedral and gold Inca statue and lots of Peruvians in town for a fiesta.
It was perfect, minus the altitude sickness. I guess my Everest is cut out for me.
