I don't know why it bothers me so much that the insides of their mouths are the same color as their skin or beard

Maybe look at old office PCs for sale. Some of them aren't THAT old and you could get a good CPU upgrade from one of them. Slot your graphics card in and that could be a significant improvement.

I see RAM at somewhat high but reasonable-ish prices on Facebook Marketplace all the time. Might not be the case elsewhere, but it's an option.

Kinda nice but I would have never guessed

How do you do another level?

You certainly did not!

Thanks! Now I get it. :)

Great explanation. Thank you so much for all the effort. But the part you explained in the most depth was the part I did understand, I'm so sorry.

But I did understand the part where I was confused anyway, to some degree

What I wondered was why giving humans that ability would make the cold extremities feel worse. The answer seems to be that by reheating the returning blood, the outgoing blood gets pre-cooled, and starts at a lower temperature. So the feet are even colder.

Now the question I still have is: so the birds' get are still super cold, probably even colder than humans'. They probably even reach freezing temperatures, considering birds don't disappear even at -20 °C. Why don't they get frostbite, lose toes to necrosis, and all that stuff that a human going out barefoot in the winter would be sure to get?

What I don't understand is that, say, for a human, if you're warmly dressed everywhere but your feet are bare, like a bird.

The danger isn't really that you'll die because you didn't have enough heat overall. The danger is the your feet will not get enough heat to compensate exposure and will freeze by themselves.

So if birds have a mechanism to survive that, I have trouble understanding how except by sending more heat into the feet overall. Unless their feet can just survive being below freezing unlike ours?

I'm so confused

Wait wouldn't more heat exchanged mean that the fingers would be closer to the average temperature of the rest of the body? That sounds comfortable to me, unless I'm missing something

I'm better than that. My organs can shut down at any temperature!

I want that. Maybe my toes and fingers wouldn't be so cold so often.
