ನೆತ್ತಿಯಲ್ಲೇ ಮೊದಲು ಕೂದಲು ಏಕೆ ಬಿಳಿ ಆಗುತ್ತದೆ ???

  ನಮ್ಮೆಲ್ಲರ ಕೂದಲು ದಿನ ಕಳೆದಂತೆ ಬೆಳ್ಳಗಾಗುತ್ತದೆ.

ಆದರೆ ನೆತ್ತಿ ಮೇಲಿನ ಕೂದಲೇ ಮೊದಲು ಬೆಳ್ಳಗಾಗುತ್ತದೆ.

ಯಾಕೆ  ??

1.  ಕೂದಲಿಗೆ ಬಣ್ಣ ನೀಡುವ ಜೀವಕೋಶಗಳು ಕೂದಲಿನ ಬುಡದಲ್ಲಿರುತ್ತವೆ. ತಲೆಯ ಮಧ್ಯದಲ್ಲಿರುವ ಕೂದಲಿನ ಬುಡಗಳು ಬೇರೆ ಭಾಗಗಳಿಗಿಂತ ಮೊದಲು ಈ ಜೀವಕೋಷಗಳನ್ನು ಕಳೆದುಕೊಳ್ಳುತ್ತದೆ.

ಹೀಗಾಗಿ ಇಲ್ಲಿ ಕೂದಲು ಬೇಗ ಬಿಳಿಯಾಗುತ್ತದೆ.

2.  ಸೂರ್ಯನ ಶಾಖ ಮತ್ತು UV ಕಿರಣಗಳು ತಲೆಯ ಮಧ್ಯ ಭಾಗವನ್ನು ನೇರವಾಗಿ ಸ್ಪರ್ಶಿಸುತ್ತದೆ. ಅತಿಯಾದ ಬಿಸಿಲಿನಿಂದ ಕೂದಲಿನ ಪ್ರೊಟೀನ್ ಮತ್ತು ಬಣ್ಣ ನಷ್ಟವಾಗುತ್ತದೆ.

3.  ತಲೆಯ ಮಧ್ಯ ಭಾಗಕ್ಕೆ ರಕ್ತ ಸಂಚಾರ ಸ್ವಲ್ಪ ನಿಧಾನವಾಗಿ ಆಗುವುದರಿಂದ ಕೂದಲು ಬೇಗ ಬಿಳಿಯಾಗುತ್ತದೆ.

4. ನಮ್ಮ genetics ಕೂಡ ಕಾರಣ.

5.  ಅತಿಯಾದ ಒತ್ತಡದಿಂದ ತಲೆ ಮೇಲಿನ ಸೂಕ್ಷ್ಮ ಜೀವಕೋಶಗಳು ಘಾಸಿಗೊಳಗಾಗಿ ಕೂದಲು ಬಿಳಿಯಾಗುತ್ತದೆ.

6.  ಹಾರ್ಮೋನ್ ಅಸಮತೋಲನವೂ ಒಂದು ಕಾರಣ.

Is yawning contagious ??

YES  .....!!!! 

Yawning is highly contagious ......!!!

The likelihood of yawning increases 6 fold , when we see or hear someone yawning  .... !!!

WHY IT HAPPENS  ??

There are several theories 

1.  It is a type of empathy.  We are likely to catch a yawn from a friend or a family member than a stranger  !!!

2.  The " mirror neurons " trigger automatic imitation of someone's yawning.

3.  If group of people in warm climate, they may yawn contagiously to stay cool.

We don't have to even see a yawn to catch one  !!!

Simply reading about or thinking about yawning is enough to trigger the reflux ....!!!

Why do we yawn ???

  There is no single scientific consensus on why we yawn !!!

It is generally  considered as involuntary reflex controlled by hypothalamus in brain that serves both physiological and social functions.

For years , people believed we yawned to  get more oxygen or expel carbon dioxide.

But breathing more oxygen does not change how much a person  yawns !!!

Popular theory suggests that yawning helps regulate body temperature. The stretching of facial muscles increase the blood flow to brain.

Contagious yawning is associated with empathy.  People who are more socially attuned are more likely to catch a yawn from someone they are close to  !!!

Yawning does not appear in new born babies.

It appears in chimpanzees, dogs, cats, wolves, lions and one species of parrot.

What does break the ice means ??

What does this idiom means  ???

"  Break the ice  " means to start conversation or activity to make people more comfortable in a social situation.

When people first meet, there is an invisible wall of silence and awkwardness.

This is            ICE         !!!

When someone starts talking ,  they are breaking this  "  ice  " so everyone can relax and open up.

In ancient times, ships would often get stuck in frozen rivers or seas.  At that time, smaller and stronger boats would be sent ahead to literally break the ice and clear the path.

Sharpness of Naseeruddin

  In the village, everyone knew how silly is Mulla Naseeruddin.

One day villagers decided to find a bride for Naseeruddin to marry. 

As Naseeruddin acts silly, villagers themselves have fixed a bride and made Naseeruddin to get married to that girl.

Now 2 days have been passed after marriage. 

Wife of Naseeruddin gave birth to a baby  !!!!

As soon as Naseeruddin came to know of this news, he hurriedly came with pen and paper near the new born.

Everyone questioned him about this behaviour. 

Naseeruddin said,   

If a child can born in just 2 days after marriage instead of 9 months, he must be able to read and write by this time   !!!!
