In The Twilight Zone: The Movie, the last story was about a group of old people in a home who are offered youth again. Almost all of them accept it – but one doesn't, on the grounds that she didn’t want to have to go through the experience of growing up again. I also remembered that because it seemed a strange decision – at least, in my teens. Now I'm older I wonder which decision I'd actually take. After all, on the one hand, it was be great to be able to return to our lives with the wisdom we have already acquired from it. But isn't that all part of growing up anyway? But isn’t there also the danger of repeating past "mistakes", on the ground that the lessons learned no longer seemed so relevant in a second lifetime? I'm sure even the younger among us have considered the advantages of rewinding life's clock - if only by a couple of years. Anyway, what would you do if offered the chance?
