The other side of string theory

String theory I really do not understand much of it other than it some how ties us to a parallel universe or more than one. Sure sounds interesting to say the least. I could be someone completely different in a parallel universe. But why would I want to go somewhere that I am not who I am? Being who I am makes me, well me. Me is not so bad. I am - not just because of myself but because of all the outside influences that have made me, me. On the other side of string theory I may be someone else for the better or the worse but I think I will stay this side of it for the sake of me.
