Me neither until I met a real case: an uncle lost his family in an accident when he was in his forties; he wanted to start over, so he marries a 25 year old woman, they have 2 kids and that was about 25 years ago (the older son is in his twenties, the younger is almost to 20).

Doing that with a woman his age is almost impossible, fertility and children health when the mother is over 30 is declining rapidly.

In any case, that made me think about life a bit different. In the same situation I would do the same.
