To the OP: Yes, I often feel that I've wasted a chunk of my life. I also just turned 40 last year and I think there is something about "that age" that gets you thinking!! As opposed to you, I often wonder if I've wasted too much time working and not spent enough time being a good mother. I used to think my choices were fine, and for the most part still do, however, there are many things I have not done with my children because I was "at work." I don't really feel guilty--it's just kind of hard to describe. But I do feel now that I maybe did not make the best choices. I got married WAY to young, dropped out of college, but was fortunate enough to be a good worker and do well professionally. But, because of my lack of college education, it has severely limited me changing jobs or branching out! So I regret that for sure. On the other hand, I've seen many people with college educations not do so well so who knows what my future would have been.
Tiggeroo--I understand what you are saying. In my marriage, my DH is a very good father and provider for us. But, he is never concerned with the fact that the kids need physicals before starting school, when the medications need to be refilled for them, how my son's asthma is REALLY doing, where to find the best lung specialist, how to get in touch with the teacher about son's food allergies, and so on. Somehow, the mothers always end up with these details. I'm sure my husband would do it if I made him, but I think it's just funny how these little details end up on the mother's plate! But if you ask my husband, he will swear up and down to you that he does it all.
And to Bob Slydell: There are always exceptions to this!!!

I know quite a few men who actually do take over and do all the "traditional mommy" things and worrying about details. In fact, my stepfather was the big caretaker for me because his job was more flexible. If you're one of them, I can see where you'd find insult with the comment.
