If you're not allowing yourself to change anything, I think an interesting question would be. "Would you go back in time to be a 'passenger' in your own body to see past events through the eyes of your current self?" It would be interesting but might be a little frightening and definitely frustrating.

I'm with most people though that I wouldn't go back and change anything. Especially if you have kids. You have next to zero chance of having the same child if you change even a second of your past so you're basically wiping any child you have out of existence.
