I mean a average human can run at his full speed for 15 to 20 mins before getting tired. Trained athletes can go on running for much more time without tiring out.  Do Superheroes like Quicksilver or Flash ever get tired due to excessive running?

We are seeing different values for how long this virus can persist on surfaces with the more recent data suggesting: copper 4 hours, plastic &amp; stainless steel 3 days and, other studies stainless steel 9 days.  What's the latest data?

Which force actually drives water so high up, since pure atmospheric pressure will only get you up to about 10 meters if you're using suction and a long straw and yet tallest trees are over 100 meters ( trees do basically have long continuous 'straws' all the way up.)

Does anyone know the name of the short story in which the characters only lived a few days from birth to death? I believe it involved a ship where time was experienced normally. I recall the story plot from my younger days, but don't remember the author or the title.

For example, say I submerged a computer mouse entirely. Assuming that I ensured that all traces of the water were gone, would the device suffer any issues?  It is my understanding currently that provided that there is no power being supplied to a device, and assuming that non-electronic damage like rust etc. hasn't taken place, then once the device is completely dry, it can be used without issue. Is this correct?

The theory of natural selection has it that individuals with better genes tend to survive and reproduce, passing their genes to their offspring. This gradual process results in a population more adapted at survival. However, due to the advancement in medical science, humans with poorer genes tend to survive and reproduce just as well.  For example, in the past, many people, excluding those with natural immunity due to some genetic mutations, would have succumbed to illnesses such as malaria and typhoid. But with better hygiene and medical treatment, these patients tend to survive.  Now, imagine a future where all illnesses including cancer can be treated. How would it impact the survival of the human race? Would we become more and more vulnerable such that our survival hinges heavily on medical technology, analogous to how an astronaut's survival is dependent on his spacesuit?

In the Harry Potter series is it clear that magically-inclined individuals (witches/wizards) will live to be considerably older than their Muggle counterparts? From the question , it is given that Dumbledore was roughly 115 years old when he died, and at that age he hardly seemed ready to kick the bucket naturally.  With that in mind, how old will a wizard typically live to be, barring accidents or murder?

I only prepare sushi rice a few times a year, so it takes me a while to go through even the smallest of bags.  How long can I keep the bag for before it "goes bad"?

In Fullmetal Alchemist when Ed goes to disprove to Rose the Sun God's "miracle" to bring humans back to life by proving that science (in the form of Alchemy) can create people by saying     Water (35 L), Carbon (20 kg), Ammonia (4 L), Lime (1.5 kg), Phosphorous (800 g), Salt (250 g), Saltpeter (100 g), Sulfur (80 g), Fluorine (7.5 g), Iron (5 g), Silicon (3 g) and trace amounts fifteen other elements.   I am wondering, is this composition true in real life? if so what are fifteen trace elements?

One of my friends said that I would die if I drank distilled water (we were using it in a chemistry experiment) I gave it a go and surprisingly did not die.  I did a bit of  and found    It said that drinking only this kind of water could definitely cause death, as distilled water was highly hypotonic and it would make the blood cells expand and finally explode and ultimately cause death.  I wanted to know exactly how much of this water on an average was needed to be consumed to cause death.

I was asked this question during an interview for a trading position with a proprietary trading firm. I would very much like to know the answer to this question and the intuition behind it.  Amoeba Question:  A population of amoebas starts with 1. After 1 period that amoeba can divide into 1, 2, 3, or 0 (it can die) with equal probability. What is the probability that the entire population dies out eventually?

If water has a low salt content, it hydrates us. When water has too high salt concentration, like sea water, it drains water out of us instead when we drink it. At what salt concentration would water leave us completely unaffected?

Please forgive the obvious question.   H2O2 vapor sterilization is deadly for the layperson but should be workable for hospitals. I can't find the small Chinese study I read the other day about it. Here are two more quickly googled sources.        2.

Although she forgot to water it for a week, the plant was still alive/live.   Which one is right?  My professor has just told me that you must use ALIVE. But I don't know why yet.

How long will it remain potent outside an organism?  I'm thinking in the context of if it can survive a couple of weeks or a month in the mail for the recipient to get infected.  Edit:  I tried looking at the WHO's page dedicated to the virus, have not found anything pertaining to my question in the PDFs there (maybe I overlooked something, I guess I'm just lacking the proper keyword to use for the search)  I tried looking at the coronavirus Wikipedia page and have not found anything there.  I did find somewhere that a flu virus would typically not remain potent for more than 14 days outside of an organism, but I'm not sure if this applies to all viruses.

People are born and grow up and die of old age in a matter of 5 days. The elders (5 days old) train children and send the most promising one on a trek across the dessert to a monolith that is the cause of the rapid aging to hopefully disable it.   I saw it on a reel to reel in the mid 90's. It looks like it was made in the late 70's or 80's. The cast was small. A few men played the elders seated in a row of chairs and the young boy who had to set out to save them who matures into a man and finally an elderly man.  I've been trying to figure out the title for years.
