It could be that they are more important for survival, therefore it's "worth" making them more robust. It's unpleasant to wake up with tingly/numb legs, but it's much better than not being able to run/defend from danger because you can't control them.

>Keith Richards is still alive... no, seriously, he is.

Yeah, and Bob Saget "went to bed, and bumped his head, and couldn't get up in the morning". The human body can be incredibly fragile when it wants to be...

Near car freeways, lead in the soil within a 500 feet has higher lead content than soil 1000 feet away. So, cars of the 1920s through 1970s burned leaded gas and left deposits that exist today. I'd bet the same is true of airports with the lead being more concentrated on the areas the planes take off over, as that is when they're burning a lot of fuel.

If you drink a bunch of water, make sure to watch your potassium level as it might drop via dilution. Potassium helps to lower kidney stones as well as being important for proper heart function. Bananas and lentils are good sources of potassium.

Yes, your ears can’t hear quieter sounds that are near the frequency of a loud sound. And some frequencies cancel out higher frequency sounds as well. This is the reason that lossy audio compression works. You can throw away all noise outside of you ability to hear. It is a significant amount of data that can be tossed.

In addition audio is collected at a certain bit rate (8 bit, 16 but, 32 bit, 96 bit). As well as at a certain sample rate (44khz, etc). Modern audio cards can sample audio well above your ears ability to distinguish the individual changes or frequencies.

We often use this to our advantage when capturing audio. For example capturing at 96 bits is similar to modern HDR cameras in that you can capture both the quietest and loudest sounds we can detect, at the same time, even if both together would never be in the same final mix. This lets us set and forget our mic gains without worrying about blowing out the sound.

They are not. Motor neurons are actors and end at skeletal muscle. Sensory neurons can be as close as the skin, making it more superficial and vulnerable to sensation.

Yeah I already understand that part. See the first paragraph of my original post.

I'm more interested in knowing what the long term effects are in a person that drinks "more water than usual", but not enough in a short span of time to cause something like hyponatremia.

Car fires happen, so do plane fires. They also have batteries that you can put a bunch of nails through and all that happens is they lose a small amount of capacity. Those batteries are on the market today. Not in mass quantities. But to think that a future battery couldn't hold far more capacity than today's batteries and be safe and have enough other good parameters for aviation is silly.

Did some googling, and it looks like only mammals have the specific protein sequence needed: https://www.cell.com/trends/biochemical-sciences/fulltext/S0968-0004(07)00060-6

Haha, yeah not for mothers lol. Those first 3 months are rough with a newborn. I have two myself (second is now 8 months) and it was almost like clockwork that at 3 months old they started sleeping through the night and it felt like we got past the super vulnerable phase. Best of luck to you and family.

Forty year old Cessnas aren't being flown by the really rich guys that have a shot at controlling regulations.

Things move slowly in aviation. Most flight schools will use aircraft built the 60s for training. They all have engins from the 60s as well.

> These neurons are located deeper in the body and are more protected by other tissues like muscle and bone

Motor and sensory neurons are within the exact same nerves. Your answer doesn't make sense
