Although I'm a vegetarian for a few reasons, it's mainly because I don't like the taste of meat. I was told by a doctor that I might have hyper-sensitive taste buds. I've heard of people not being able to taste much at all, which I'm guessing i... | explainlikeimfive | https://www.reddit.com/r/explainlikeimfive/comments/46y2y7/eli5_why_do_humans_have_different_taste_buds_from/ | {

fz1v23 | why are there more dangerous animals (and insects and fish) in hot countries? |
Dangerous to humans I mean.

Is there just an insufficient gain to be had in that scenario to justify the additional construction cost for the house and the fridge?
