You ever wish you had a time machine so you could go back in time and stop yourself from doing something or maybe do it different I spend a lot of time thinking about that. The ironic thing is sometimes even if you did have a time machine you would leave things as they were, because even if changing them would make now easier, it could make you loose yourself. Let me give you an example do you remember the first terminator movie? Remember where she finds out her sons best friend in the future is his daddy. The writers of that did not have a clue. For him to get into the future the first time he before time travel was invented someone else would have had to have been his dad. Which means when his friend stepped in to be his dad which means he would not have been the same person he was the first time he went back in time. Sometimes the past is not men to be changed.
