TIL about Tetrachromacy, a condition which lets you see more colors. Normal people can see about 1 million colors, while tetrachromats may see up to 100 million. Up to 12% of women may have it. (www.healthline.com)

I'm heterozygous for cystic fibrosis. It fucked my plans for having kids, cause I don't have vas deferens. (Most people who are heterozygous don't have any problems, but some men do with fertility). But apparently heterozygous people are more resistant to cholera and dysentery, since our cells hold onto water easier.
