If you have kids in your 40's you're a terrible person. Hope your kids enjoy growing up with parents that can barely handle their energy levels and get to watch them decline in health and die in their early 20's.
there's a big difference between being infertile due to genetic disposition/bad luck and being infertile because you waited until your mid-40's to have kids. My point is aimed at the latter although you already knew that and just wanted to be a snarky little shit
