I know this post is already closed, but I can't let it go without my comment.

My favorite age I'd like to go back to is when I was 4-5 years old but with all the knowledge I have now. I mean, I don't really remember a lot of things from that time, but there are some things that happened when I was 6 that I wish I could avoid.

I don't want to give details, but those things changed my life completely and I wish it was different.

There's also the fact that when I was that age the magic of Christmas was so much more special than the years that followed. I wish I could experience that again.
