Thanks for the interesting input, Teclo. Allow me a few comments:

It's hard to draw a line. Different people age differently and even young people can be incredibly unhealthy.
Yeah, of course, and no-one contests that point. But for the sake of abstraction, we must compare average cases, not individual cases. And there
are widespread, age-based reductions in bodily and mental (alzheimers!) competence that make child-rearing in the average 60+ less responsible than in the average 20+ group. Also, there
is an overwhelming tendency in the elderly to adopt an end-fixated perspective (Fiehler 1997 and 2003; Nikander 2002) and that is absolutely devastating to a child.
Now, on the other hand, if in each case their mothers had been about 60, but totally clean and not related to the father, they would have both been born in far better condition.
Absolutely. However, a child of totally clean and non-incestuous parents aged 20+ would likewise be likely to be born and raised in far better conditions than one of totally clean and non-incestuous parents aged 60+.
There are also outside factors, like crime. I mean, should we stop people that live in crime ridden areas from breeding?
Of course outside factors come into play, but the original question was about the impact of age ^.~
Also, I didn't make a case for stopping anyone from breeding, I just advocate making a responsible choice.
Besides people can die at any age.
Of course. But mortality skyrockets with age.
He'd probably have preferred an ancient old dad than a pissed up one that topped himself after 13 years of having a son.
Probably. Who knows? I'd have preferred no father to the one I had. But all that is idle speculation based on single cases.
