Read people's minds: Nope, really don't want to know what they are thinking as they look at me or talk to me or work with me. And I do'nt have the self-control to only do it occasionally.
Fly: OK, fun, but really, what use is it? Unless you can carry a full trailer of camping gear and people and everything you need for a vacation.
Be invisible: Again, fun in certain situations, but do I really want to spy on people? Certainly not on the people I know, (TMI!!!) and on people I do'nt know ... I just think the novelty would wear off really, really fast. And I am certainly not the type of person who would use it for illegal gain.
See through walls (and everything else): Um, again, what use is it really? And how distracting to be watching something but also be seeing through it (and where does it end, anyway? If I am sitting on the couch watching TV, I would also see THROUGH the TV, through the wall behind it, through the wall behind that, and so on and so on. How could you focus?)
Super-human strength: OK, so far this one has the most potential, never have to ask for help to open a new jar, be able to pick the car up and put it in that tight parking space, rearrange the furniture without having to empty the bookshelves first, yeah, this one is growing on me.
Invincibility: I worry that this one would be like that disease some kids have (that they always use as a story line on doctor TV shows because it's so sensationalistic - that, and Munchausen by proxy) where they don't feel pain - would I even notice my hand had been cut off? Or does this mean that a saw could go through my arm but it would refuse together as soon as the blade was past? But then again, how often am I in mortal danger, and is it needed for the occasional stubbed toe or paper cut?
Hmm ... so I guess the strength one seems to be it for me. What other powers have I forgotten? Stretchiness like Reed in Fantastic Four or the Mom in The Incredibles? Speed like the kid in Incredibles? Neither of those are of much interest. But perhaps I am not realizing the true advantages to some of these gifts.
What would you pick?
