I was born several decades prematurely. A world without space travel? You can have it. 
I was born a couple months early, checked in at a bit over 4 lbs.
Twins have a tendancy to be premature. It was 1967. I came into this world feet first. I’m 6 feet, 185. No glasses, no freakish abnormalaties, except for a deviated septum and a shitty right knee. My brother is an inch or two taller. He wears glasses and went prematurely grey, but that could be easily written off as genetics. My brother and I spent time together in the incubator until I peed in his face.
I think any study may very well exclude twins, just to limit any variables, so there’s my $.02
Four weeks premature (or was it six)?
6 foot 6 and a half, 140 kilograms, and four degrees.
But i have crap eyesight
Three months premature, here. I have small stature (five foot four, 49 kg) but am the exact same height as my mother, so that may not have anything to do with it. I do have bad eyesight (although, when I’m wearing glasses my eyesight is better than most people’s), and weak arches in my feet.
Oh, and I was born with a hole in my my heart. I was forgetting that.
