Q1         Whyis human waste considered an environmental hazard that needs to 
be cleaned,when every other animal in the world does it anywhere?

A1         JoshuaEngel, Worked at The Rude Mechanicals Jun 8

Human waste contains the kinds of bacteriathat infect humans. Your immune 
system has largelyadapted to deal with your own personal set of bacteria, but 
other humanshaven’t. Their bacteriacan run amok through your body before your 
immune system has a chance to catchup, which will make you very sick and can be 
deadly.

For the most part, other animals’bacteria can’t live in humans. Bacteria are 
really pretty fragile,and require specific conditions. A cow’s digestive tract 
is very different from yours. Diseases dosometimes jump from one species to 
another — and when it does, it’s often verybad. COVID and HIV are examples.

And note that it still happensanyway. Chickens give ussalmonella; cows give us 
E. coli. This is caused partly by the way in which weraise those animals in 
vast factory farms, often with antibiotics that causebacteria to evolve more 
dangerous forms.

Animals out in the wild do give eachother diseases all the time. They do get 
sick and die. Wild animals live muchshorter lifespans than pets, and diseases 
are one reason.

Mynote- Very beautifully explanation. On this account, if a person is having 
majorhealth problem, particular toilet is used ( eg- Covid period )and more 
fleshingis done and sanitation items  are appliedmore times.

Q2         Isglass actually a liquid, as some people have tried to tell me?

A2         MatsAndersson, M Sc. in Physics & Computer Science, Uppsala 
University(Graduated 1991)Mar 15

Not really.

It doesn’t have a crystal structure,which means that theoretically, it might be 
an incredibly viscous liquid.

 But we have glass vessels fromthe Roman Empire that haven’t changed shape in 
all this time, so it’s not likeany flowing would happen even on historical 
timescales.

The idea that old glass in windowshas been flowing, and that this is why the 
panes are thicker at the bottom, isa complete myth. The glassmaking technique 
forproducing sheet glass wasn’t very advanced before the mid-to-late 19th 
century,so old glass tended to come out a bit uneven in thickness; medieval and 
earlymodern glaziers, not being complete idiots even though they lived long 
ago, put the glass in windows with thethicker end down for better stability.

My note- The QA is added for the chemical property of glass- No 
crystalstructure. Probably on this account it breaks often. With fibre glass 
itis changed and hence used for doors, stove tops etc. 

Q3         Howwere the differences in time zones first noticed?

A3         SilkRoad, AI Expert2h

Backin the day, before trains and planes and cars, people didn't really care 
abouttime differences.

They just used the sun as theirclock, and set their watches to noon when the 
sun was at its highest point inthe sky.

Thatworked fine for local stuff, but it got messy when people started 
travelinglong distances.

Imagine trying to catch a train that runson a different time than yours. That 
would be a nightmare, right?

Well, that's exactly what happened to Sir Sandford Fleming, a Canadian engineer 
who worked onthe railways.

In 1876, he missed his train because his watch was off by a few minutesfrom the 
local time.

He was so annoyed by this that hedecided to come up with a better system for 
keeping time around the world.

Heproposed dividing the globe into 24 time zones, each one hour apart from 
thenext.

He based his idea on the fact that the earth rotates once every 24 hours, and 
there are 360 degrees oflongitude, so each hour corresponds to 15 degrees of 
longitude.

He also chose Greenwich, England as thestarting point for his time zones, 
because that's where the prime meridian islocated.

His idea was pretty brilliant, and itcaught on quickly among the railroad 
companies, who needed a standard way toschedule their trains.

In 1883, they adopted Fleming's time zones in North America, and calledit "the 
day of two noons" because some places had to adjust theirclocks by more than an 
hour.

A year later, an internationalconference in Washington D.C. agreed to use 
Fleming's system worldwide, and established GreenwichMean Time (GMT) as the 
universal reference point.

Today, most countries use somevariation of Fleming's time zones, although some 
have tweaked them to suittheir needs. China hasonly one time zone for the whole 
country, even though it should have five.

Australia has three time zones, butone of them is half an hour ahead of the 
others.

And some places use daylight saving time to adjust their clocks by anhour 
during summer or winter.

My note- Though I studied green which mean time in middle school, I have least 
recollection of theincidents told. BeforeIST, I read elsewhere Chennai time was 
lesser than an hour of Calcutta time.

Q4         Whyhaven't humans learned to take laxatives and use our body waste 
as compostrather than using animal feces?

A4         StevenHaddock, Studied at York University (Canada)Nov 7

Humans started using their own feces ascompost pretty much as soon as 
agriculture was invented. The practice continuedin many places well into the 
20th century.

However, the practice soon proved tohave a lot of drawbacks. Humans in the 
early agriculturalera didn’t know about bacteria, and crops fertilized with 
human dungoften caused outbreaks of disease because those gut bacteria 
persisted in thesoil until they found a new human host.

As such, people learned that althoughit was fine to plant cereal crops, or any 
plant with a long stalk in suchfields, and not to plant carrots or other root 
crops for at least a year. Bythat time pathogenic bacteria had usually died out.

Because horses, pigs and cows don’tshare a lot of gut flora with humans, it was 
soon found using animal dung hadthe same effect with fewer drawbacks. It was 
perfectly safe to use a few acres of land as cattle pasture for ayear, then 
plant the following year.

Q5         Whatis the legend of a married person pretending blind for wife’s 
happiness?

A5         CrystalRoss,5h

A man married a beautiful girl. Heloved her very much.

One day she developed a skin disease. Slowlyshe started to lose her beauty.

It so happened that one day herhusband left for a tour. Whilereturning he met 
with an accident and lost his eyesight.

However,their married life continued as usual. But as days passed she lost 
herbeauty gradually. Blind husband did not know this and there was not 
anydifference in their married life.

He continued to love her and she alsoloved him very much. Oneday she died.Her 
death brought him a great sorrow.

 

He finished all her last rites and wanted to leave that town.

Aman from behind called and said, “Now how will you be able to walk all 
alone?All these days your wife used to help you”.

He replied, “I am not blind. I wasacting because if she knew l could see her 
skin condition due to a disease, itwould have pained her more than her disease. 
Ididn’t love her for her beauty alone, but I fell in love with her caring 
andloving nature.So I pretended to be blind. I only wanted to keep her happy”.

Moral: When you truly love someone, youwill go to any extent to keep your loved 
one happy and sometimes it is good forus to act blind and ignore one another’s 
short comings in order to be happy.

The Beauty will fade with time, butheart and soul will always be the same.Love 
the person for what he/she is frominside, not from outside.
