Updated 40 things before 40 - need help with the last nine

I'm up to 31 items now.

Have ANY idea how hard it is to come up with 40 things?
If you're going to do one of these list, I strongly recommend you do it before you turn 30, 31, 32, pick your year etc... The older you get the harder its becoming, cos I've done a lot already.

9 more to go. I need help. Suggestions please.
