Inca Heritage

Today I came back from almost 2 weeks in Peru: I stayed mainly at Cusco and then in Puno and Lima, visited 6-7 smaller cities, various villages, settlements, went to Machu Picchu,  took a trip on Lake Titikaka where I stayed a night on Amantani Island after visiting Uros and Tequele islands.  Peru is beautiful, Peruvians are very nice, peaceful people.  I wouldn't mind living in Peru permanently in a place like Cusco.
The altitude however is too high for me: I had to chew coca leaves all the time to prevent dizziness.  It's the highest point I ever visited.
