Yes, travelling the world is the best! Glad you're in the same boat as me.
I, too, wish to go to East Asia -- particularly South Korea because of their interesting culture and advances! The Amazon sounds wonderful as well...but too much deforestation there so it's depressing...plus all the other habitat destruction that is taking place...we humans will definitely cause the next mass extinction! Anyway, my travels would focus on the environmental aspects since I absolutely love the environment (water, earth, wind, etc.!). South Korea protects its environment fairly well and has a government that does exactly what every country should do to hopefully mitigate and combat climate change!!!!
Sorry, off tangent, but yes, China is pretty amazing, too! The scenery is breathtaking...but the major cities are all polluted....
