> Whether it's through DNA or a book, this is the way our species evolves each generation. That's a great point and although I am currently raising a toddler I really don't feel that I've 'contributed' to society or humanity in general at this point. Many colleagues talk about their hope that their kids will 'grow up to do something great' but that's abstract and wishy. My wife was very keen to have a child before she was too old to accept the risks, so we did so. But I'd much rather have put the time and money into research for a book that would propagate at least a little knowledge forward in time.
