Whoa whoa whoa. I don't agree with that at all. I'm not like Khane at all. He's basically Jerry Seinfeld, but pickier. For me it's more a matter of just not being overly good at the initial meeting of women. Typically once I get my foot in the door, I do fine with women, at least in the initial stages of the relationship (I screwed up the later stages with the last woman, but that was literally my first kick at one longer than 6 months). But the main reason I haven't been in a lot of long term ones isn't that I just toss chicks aside on the regular, it's because I start so few relationships in the first place. In my day to day life in the construction industry, and also in my main hobbies in spare time (hockey, biking, skiing, camping etc), I meet essentially zero eligible women. And being in my mid 30's, most of my friends are coupled off, and any potential friend of friend set ups have mostly been exhausted. So outside of online dating, which I haven't really invested much time or effort in, there's just not a lot of opportunities coming my way.
That's not true at all. The age of the man most definitely impacts defects and shit like Downs, Autism etc. The maternal age is most important, no question, but paternal age has an impact as well. But we're talking men who are 50+.
