Is there a point as the temperature drops that it stops feeling colder? in other words, once a certain temperature is reached does it all just feel the same after that? | [
"You don't feel temperature directly, you feel the rate at which heat leaves your body. So it really depends on the material's heat conductivity and how it's arranged as a heat sink. Generally, the rate of heat transfer is inversely proportional to temperature, all else equal, and since you can't reach absolute zer... | [

Why is it, that when we eat something spicy, like a Jalepeno, we have a harder time eating food that is hot (temperature wise)? | [

Why does being wet make us sensitive to wind? | [
"Evaporation sucks up heat. Wind/moving air increases the rate of heat transfer between two objects, and so it makes the water evaporate more quickly. This is why you sweat - it cools you off.
