hiimjosephfink said: Why does mint feel cold and chiles feel hot?

scishow:

So, the way we experience…pretty much everything is via proteins and ion channels. Very basically…there are proteins that are designed to sense certain things….the presence of sugar, whether they’ve been struck by light, the concentration of CO2 in the blood. When they sense those things, they open an ion channel changing the electrical charge of the cell, which then get transferred through the nervous system to the brain where that area of the brain is like “Cool…we’ve got sugar…or light…or too much CO2 in the blood.”
Well, sometimes these proteins can be fooled. A chemical will, just by chance (or by natural selection) be able to bind with that protein and cause that whole cascade to occur without the real stimulus. This is what happens with menthol in mint and capsaicin in peppers. Those chemicals bind to the cold / hot receptors respectively, fooling your body into thinking that something cold / hot is happening in your mouth. Pretty cool.

white people: mike brown robbed that store!

Lawyer: no he didn’t

Store owners: nope

Eye witnesses: nah

white people:

white people: MIKE BROWN ROBBED THAT STORE

I’m gonna be honest here I do not understand why this has to be all white people versus all black people yep in the section of people condemning brown it is almost entirely white people condemning Brown but the camp defending Brown also includes white people are and I don’t see how reducing it to such helps racial relations. If somebody could explain to me I am listening 100% no sarcasm intended
