It is a natural extinct of bat to use one path to make a safe exit and avoid a possible collision. It is general perception that bats always use left path to make an exit which is not true. Depending on the cave path they can turn right as well. No restrictions or whatsoever.

Yeh bhi aik sooch he aur jitnay moun utni baaton wala concept he. Medical research aisa kuch bhi explain nahi kerti.

Basically is ke peechay aik concept yeh tha ke jub aap sneeze kerte hein to aap ki heatbeat for a fraction of second ruk jati he aur dimaag ko blood ki supply band ho jati he jis ki waja se dimaag ke kuch cell dead ho jatay hein. It is simply a dull idea. Jitnay moun itni baatein. Aisa kuch bhi nahi hota. Sneezing is a natural phenomena to excrete out unwanted dust particles / pollens etc from nasal cavity. It produces a lot of force but doesn't affect heart or brain. Ager is se dil ruknay lagay ya dimaag ki cells merne lagein to jisay pollen allergy ho jaye wo to gaya kaam se.

Question ~ Why is the sky blue?

Answer: Violet and blue light have short waves which are scattered more than red light waves.
While red light goes almost straight through the atmosphere, blue and violet light are scattered by particles in the atmosphere. Thus, we see a blue sky.

Blue and violet are firstly absorbed by atmospheric particles and then are radiated to various directions.
