When do you consider someone old? I think you are as old as you feel; a great example of this is the flying granddad. He is over eighty years old and is competing in races. But not just any old ordinary race, things like the race to the sky and the rally NZ. Another example of this, although it’s fictional, is the Emperors new grove 2, Kronk’s new grove, Kronk scams the oldies into thinking that he’s selling them youth potion but it’s a fake. The oldies all think its working and do things that they could never other wise, but because the potion is fake, it has no physical effect on them, all the things that the did were because the felt younger, not because of the potion. So this proves that you are and always will be as old as you feel.
