I rather be trapped in the antarctic because I can always wear tons of cloths to get warm, while in the desert not even naked will do be enough to get cool.
You were given a chance to visit new worlds and see things no other human could see or imagine, including knowledge and start a new life there. However, you had to leave your own world, family, friends, home, job, everything, behind and never see them again. Would you go or stay?
