I'd rather be myself
I alway wonder when this question is asked: If you could "be" someone (i.e. Tiger Woods), would you still be yourself on the inside (have the same opinions, likes and dislikes, etc) and just take over the other person's body (and hopefully, their talents/skills, or you're going to have a shockingly muggy return to the golf course
Or, is it like you make the choice and instantly lose you current self, your personality, your consciousness of who you were 'before' and really become that other person, with their tastes, their phobias/ interests/ idiosyncrasies, etc.?
I think this is pretty important to know before answering.
