Body swapping? Put your soul in a young body and then in few or a douzen years do the same again? Only issue if you swapped into the wrong body...
What if... I mean... What if... I get attached to one of those bodies? Uh? What then??? What if... it's ... I dunno... out of the top of my head? A MILF with a taste for big titted red heads? Uh? What then? Uh? How do I say good bye??? Uh?
Nah, that's too many chances for a large number of heartbreaks...
Imagine... say good bye to... to... to... that!
Peace
