I'm not butthurt or anything
but for strictly educational purposes I will say my dad was 43 and my mom 40 when i was conceived.
I have no health issues and rarely get sick, and no mental issues other than ADD (and whatever brand of autism has led me to this website). I also misbehaved as a kid but i largely blame that on the fact that i was raised on vidya and 90s cartoons, and a classroom is an objectively a retarded place to put a kid for 7 hours.
Also worth noting: both my parents were and remain extremely healthy, both lifelong athletes, mentally active, don't eat garbage or smoke, etc. They're in their 70s and workout every day, have no health issues, no hair loss, no problems getting around our remembering shit.
Obviously everything is converging statistical dice rolls, and it's undeniably better to conceive in your 20s than 40s, but there are other factors.
