This is something I often think about...
If you could go back in time, would you change anything? I'm not talking about making a note of the winning lotto numbers, or anything for personal gain, I mean things like trying to prevent 9/11, or human suffering?
If you could go back, would you want to change anything, or do you think it would be best left alone?
Might seem like a stupid question, but I'm sure most of you have had this kind of thought.
