Another thing you can do right now is to start asking your parents about their life. It's one of those things you never take the time to do, and then one day it's too late.

If you live close to your parents, do it in person the next time you see them (and bring a voice recorder, your grand-kids will thank you some day). If you live far away, I built a service that makes it easy to do over email (http://www.storyworth.com).
