Why doesn't stomach acid burns through our stomach ??

 If we are about to get an acid reflux, we feel a burning sensation when acid from stomach escapes into mouth.

This means stomach acid is harsh enough to irritate the inside of our throat. 

Why doesn't stomach acid burns through stomach ??

Stomach produces gastric juice to aid digestion. The main component of this gastric juice is hydrochloric acid.

It is strong enough to dissolve metal  !!!

Without protection, this strong acid would quickly begin to eat into stomach wall first forming painful ulcers before ultimately burning a hole.

However, cells that line inside of stomach called epithelium produces a very thick, sticky layer of mucus  which is alkaline and buffers the strong acid.

This layer is continuously renewed.

But when this layer is damaged, problems start.  Small breaks can allow acid to penetrate into mucus layer which can lead to inflammation and ulcers.

Avoiding acidic and spicy food and lifestyle changes help to relieve the suffering.

 Question 

Ramesh Rao working in a company got a salary increment of 10% for good performance in his job.

After 2 months, company realized that increment was for another employee Ramesh R, and not Ramesh Rao.

An instruction was given to accounts department to reduce the salary of Ramesh Rao by 10% and increase the salary of Ramesh. R. By 10%

From next month, Ramesh Rao started getting a  salary lesser than what he was getting prior to his promotion.

How did this happen and what is the %ge decrease in salary??

Answer 

Let's assume Ramesh Rao's original salary was 100 Rs.

After 10% increment, salary  =  100 +  10% of 100

                                                          = 100  +  10

                                                           = 110 Rs

Then  10% decrease on 110 Rupees.

==>>   Decrease  =  10% of 110

==>>   Decrease  =  11 Rs

Ramesh Rao's new salary  =  110  -  11

  ==>>   New salary  =  99  Rs

Percentage decrease =  ( 100 -  99 )  /100

     ==>>     1%    !!!

Why is there a hole in middle of medu vada ??

 Medu vada is usually thicker in shape.

We can make vada without a hole at the middle  !!!

But at that time, only the outer part of vada gets cooked.  Not the inner part.

By making a hole in the dough and then frying in hot oil makes both the sides to get cooked uniformly and it gets crispy.

Surface area of medu vada increases by making a hole at the middle.  This makes vada to stand steady when frying.

Extra oil which is not needed will flow out easily thereby making the vada smoother and crispy.

Why dogs often choose to sleep near entry points ??

 Dogs are instinctively wired to monitor entry and exit points of their environment.

This bbehaviour traces back to their ancestors who positioned themselves at dens entrances to detect the threats, protect the group and control access to resources. 

Sleeping near doors allows dogs to stay alert to sounds, movements and changes in their surroundings.
