There is something happening, but now it has to be said!
Do you know?
Every time a human is wiped with his butt
is actually a last resort! ! !
You may ask, what the hell?
"Don't you want to wipe your butt?"
"Are you waiting for me to wipe your butt?"
"You can't do something secretly on your back when you go to the bathroom alone?"
"Is it possible that you can be arrested and go to jail without wiping your butt?"
Uh, what are you thinking?
I don’t mean this~
I mean from a biological perspective
Human beings have to do it
In other words, do you think animals don’t need to wipe their butts?
But if you don’t wipe it, it’s true! of! No! OK!
If you don’t believe me, I’ll take you to learn more about
Wipe your butt
The most direct reason
is the price paid by humans after walking upright
Want to walk upright
Humans must have a powerful and round butt
[To be honest, you really can’t find a rounder butt on the earth than humans]
But a round butt also has disadvantages
This structure leads to the distance between the legs Become very close to
Muscles and skin must be close to
If you don't wipe your butt
will inevitably be confused for a while
[I'm talking about shit on the butt smearing all over your butt, referred to as "confusing for a while"]
After walking upright
After walking
After the human excretion organ is located directly below the human body
and most reptile excretion organs
are at the back of the body
This change in humans is actually very inconvenient
because urethral , genitals and anus
very easy to affect each other
If you don't wipe your butt
It is easy to cause some hygiene problems
For example: urinary tract infection , anal inflammation
Many animals have a magical skill
that is, when you defecate, part of the rectum will be released outward
0 Defecate basically. It will dirty itself
This "creation" is simply a magical stroke
is like a faucet connected to a water pipe
directly made it into the intestine
does not stick to the body
, and humans are more miserable
Due to changes in muscles and pelvis
Human rectum not only cannot be turned outward
but it is easy to cause another problem
So animals do not need to wipe their butt
itself is also clean
But humans are "clean and innocent" for their own l1
It's really not possible to wipe it without
Many animals don't wipe their butts
is because the shape of the poop is better
doesn't make the butt dirty at all
For example, wombat
square
looking at chocolate-like
. Modern people's eating habits are very complex
and the intake of water is much higher than other animals
causes humans [it's easy to get sparse]
Poop has a very strange feature:
If you don’t believe it, you can try
and try it and die
Hahahaha
It’s really not okay without wiping your butt
You go there and poop and go there
There is another very important reason
is when you shit
is one of the most vulnerable moments in an animal’s life
If you have observed your dog
you will find that it often looks when shit
You
At this time, they can't fight or escape
In the wild, so they are likely to take their lives on
versus wiping the butt
or pulling it and leaving quickly is more secure
but humans are just the opposite
In order to prevent the death of the society
or pulling it and it's safer
to prevent the death of the society
or pulling it and it's safer
stool in the eyes of animals
and the poop in the eyes of human
is actually not a thing
Many animals use the taste of excrement to release information
for courtship or marking activity areas
even some animals will eat their own poop
to intake some nutrients
So whether to wipe the butt
is not important to animals
but when people come here
The status of poop is very bad
For example, animals can use poop to occupy the territory
Do you dare to use poop to occupy the library?
Actually,
is not all animals
don’t care about their butt
For example, cat’s butt is very clean
