Why do Indian trains have ' X ' mark on last coach ???

 We all have seen the bold "  X  "  mark painted on last coach of the train.

Here are the reasons   ------

1.           Primary reason is to confirm that entire train has passed through a station without any coaches left behind.

               It is perticularly vital during night operations and in areas with low visibility.

2             The absence of '  X  '  on last coach serves as an immediate indicator of an emergency situation.

             This practice helps in   preventing potential accidents and ensures the safety of passengers as well as railway staff.

3.              At night, a blinking tail lamp is attached to the last coach to provide confirmation that the train has passed fully.

4.                 To ensure that '  X   '  is visible under various lighting conditions, railway authorities use various reflective or radium paint. 

                    This enhances the visibility of  ' X '.

Why do we sneeze multiple times ??

Today morning, I had written a blog article on what happens in our body when we sneeze .

We rarely sneeze once.

Atleast we sneeze 2 to 3 times continuously   !!!!

If we sneeze in a row, it is because the first sneeze didn't quite get the job done  !!!!

Often the first sneeze breaks up the irritant.

Second moves it.

Third finally launches it out   !!!!

Doctors recommend 

WHAT IS COMING NATURALLY ,  DON'T STOP   IT   !!!

What happens when we sneeze ??

  We sneeze primarily to expel irritants from our nasal passages and protect the respiratory system.

It is an involuntary reflex reaction.

Now I am going to explain what happens when an irritant enters our nasal passage  !!!

1.  When irritant enter our nostrils, they interact with tiny hair and sensitive skin.

2.  This irritation stimulates the nerve, which sends an electrical signal to " sneeze center " of our brain stem.

3.  Brain coordinates a massive muscular response.

     Eyes shut.

     Tongue moves to roof of the mouth.

      Chest muscles brace.

4.  Diaphragm contracts 

    Air is forcefully expelled through nose.

    Speed of air can reach upto 100mph  !!!!

5.  Finally irritation is cleared.
