I remember Shlup's long term plans. It scared me because I can barely plan what I'm eating for dinner much less what I do next month. Thinking about next year is unfathomable.
That said, being a male, I don't have a biological clock. Just yesterday I mentioned that I'd like to have a kid after I turn 65 - that way I'll be dead before the kid turns 18 (hopefully). Yay. Maybe I should get the kid when I'm in my 70s instead.
