Lol, don't take it that way... you're just high mileage. You're still cool. 
My parents were slightly accidental *cough* (my sister was planned though) - my mum was less than thrilled at becoming a nana at the advanced age of 39. 
High mileage is right, along with overdue for routine service, but all my cylinders are still clicking and all my plugs are still firing. I have never really been "cool", though.
My mom was married at seventeen and became pregnant, within three months, I was born two months after she turned eighteen. I was usually embarrassed, as a teen, to be seen with her in public, because at thirty three (I was fifteen), she still looked well kept and kind of pretty. Guys would always ask who that chick was, I was with. "SHE"S NOT A CHICK! SHE"S MY MOM! FUCK, the fuck, OFF!"
