Superhuman powers

Which power of a super hero I would like to have? Why?

Super strenght and the ability to fly, because being strong I can fight against everybody without fear and also I can use my ability to fly to attack by air or to scape if I want it. Besides flying I could travel around the world without paying and that would be ideal.

Which power of a super hero I really would not like to have? Why?

Inmortality, due to the fact that I do not want to see all my loved ones die before me. I mean that being inmortal I would suffer a lot so I prefer being just mortal.
