I believe in solving problems, not sharing them.


Did you know that birds breathe completely differently than most animals?
We breathe tidally. Air flows in and out of our lungs. I always thought that was stupid. Why aren't our lungs more like our digestive system, with one- way flow? Not only does stuff get stuck in the dead ends that are our lungs, we never get 100% air exchange.

Birds actually have one-way flow thru their lungs, lucky sods.
