Under the sea! The challenges and setting (a bio-dome I imagine) would be similar, but with better scenery and an abundance of life. I am terribly afraid of heights and depths, but I could probably get used to living an a bubble on the sea floor. Much better than going into space, certainly, where you cannot stop falling through blackness.
Would you rather have the ability to see the future, but no one will ever believe you about your predictions? Or have wings you can fly with but that are very dangerous to use (like an extreme sport)?
