Why Do We Like Hot and Cold Food?

You take bite of piping hot pizza and burn the roof of your mouth, or you suck down a frosty milkshake and get 'brain freeze.' (Yes I know heat can burn and cold can freeze.)

Why as humans do we enjoy hot food? Or why do we enjoy cold food?

Now I am not talking about why we cook food, some foods can not be eaten raw or uncooked. And that some foods require a heating process to amalgamate or coagulate into a final food.  Also I am not talking about food safety and that we have to keep certain foods at temperatures for spoilage reasons.  I also understand that some foods are easier to digest in a warm or cold state. I am asking why we like foods hot or cold?

Other species do not heat their dinner to a temperature to enjoy, or chill it as a treat. Is it solely because man has the ability to control and use fire? That we can refrigerate items?

I personally know that we can be temperature sensitive, that hot or cold things can bother an achy tooth.

Why do we like our foods at different temperatures? I am sure there have been studies done, but I want to know what everyone else thinks.

Bring on the Biblical Floods

I am by no means a religious man, nothing I have seen has ever convinced that a god exists and has done anything for man. If something ever happens to prove the existence of a god(s), I will reevaluate at the time. But for now I remain a man of science.

But maybe it is time for any god to show its hand and bring back the floods. You know the one, that supposedly cleansed the planet of all sin, yes that one. 

Looking around the world and what is happening currently, now would be the time to eradicate the earth of its sins and sinners. The politicos and their ill regard to people, the surge of sexual predators being exposed, the average man's disrespect for the planet. 

Maybe some are right and we need not heed the climate change, let the seas rise and wash the land of the Gula, Luxuria/Fornicatio, Avaritia, Superbia, Tristitia, Vanagloria, Ira, and Acedia. (And why do they call them the seven deadly sins when there are eight?)

I am sure the world has been this way forever, just now the cesspool has gotten full and the lid has floated off it and we are being exposed to the shit mess we have made. Some maybe enjoying the fertilizer, but to many the smell has become unbearable.

Here is to an appearance of a higher power, now would be the time to prove an existence...

What if the World Lost Oxygen for 5 Seconds

What if the world lost oxygen for just 5 seconds....

• Everyone at the beach would immediately get sunburn (even though there would be no beach, no sand, and no water), because molecular oxygen in the air protects our skin against UV light.
• The daytime sky would get dark, fewer particles to bounce light means a dark almost black sky.
• All pieces of untreated metal would instantly spot weld to each other, the only thing preventing metal from welding together on contact is a layer of oxidation.
• The earth's crust would crumble, as oxygen makes up 45% of the earth's crust.
• Everyone's inner ear would explode, because we would lose about 21% of the air pressure.
• Buildings made of concrete would turn to dust, oxygen is an important binder in concrete.
• Water is a third oxygen, without it hydrogen would turn into a gaseous state and expand in volume.
• The oceans would evaporate and bleed into space.
• Without oxygen, hydrogen is free to float to the upper troposphere and eventually into space.

To be positive, now, what if the amount of oxygen doubled...

• Paper airplanes would fly further.
• We would get better gas mileage.
• Extra oxygen would improve our cognition, alertness, and physical performance.

(Also, there would be giant insects, as an insect's body size is determined by the proportion of oxygen in the atmosphere.)
