Your last paragraph also explains why cars can go 120+ when speed limits generally max out around 70. They have that power so they can accelerate quickly when they need to. The top speed is just a byproduct.

Your time is very much appreciated. Get some rest if you can. Thanks.

I think you're asking why there are tax credits and tax deductions.
Deductions reduce the amount you're liable for.
Credits act as if you already paid that much in.

Reply to ELI5: Why do we get old? by Enzo-chan
here's a not very satisfactory explanation that i found when playing with genetic algorithms at uni:
if you don't age, you end up competing for resources with your offspring. the best way to win that competition is to generate offspring that are worse than you. this leads to genetic stagnation and makes your population vulnerable to changes in the environment.

There is a solid wall of nothingness at the edge of the universe. It took years after inventing numbers for man to invent zero. So absolute nothingness is literally impossible to imagine. It is like trying to imagine a 4th direction in space except there are no directions at all. It is not empty space filled with nothing, it is nothing absolute.

The prefixes hypo- and hyper-, from the Greek, mean below and above, respectively. Hyponatremia and hypernatremia (too little and too much sodium in the blood) are easily-misspoken medical conditions.

Weird that two prefixes so close would be so different

Ab- means from. It's a different prefix than a-. Ab-origin-al means the ones who have been there since the beginning, at least etymologically.

Aborigines is Latin for "original inhabitants" and was adopted into mid-17th century English as aborigine. The English named the native people living in Australia aborigines because they were he original inhabitants of Australia (or at least they were there when the British colonized the place).

Electrical resistance. How much current you're conducting when exposed to the tiny voltage in the handles. It's a tiny current, but not too difficult to measure. Way below what you'd feel as an electrical shock.

I like how you spelled brake correctly once, but the other three times you used the word you spelled it break.

But it works while jogging? How does it manage to find the pulse amidst the constant changes of pressure?

Abnormal is more normal in this sense, oddly enough.
"Ab" as a word of its own means from, but ab-the prefix usually means "away from" for whatever reason.
So...abnormal = away from normal. Perfectly sensible.
Ab origines, as two words, means from the beginning. Okay, that tracks.
Aborigines, one word, should mean away from the origin/beginning. Wait...what? It's like we lost the space over the years and because latin is stupid and arbitrary sometimes should have inverted the meaning but we kept using it.
