Unbelievable Facts about Tears

Some people Cry while eating or smelling food or even at mere site of food or even thinking about some delicious meal and vice versa. This is called "Crocodile tears syndrome".


Some people cry without tears because of a genetic disorder that results in lacking the ability to produce tears (alacrima).

Crocodile tears (or superficial sympathy) are a false or insincere display of emotion such as a hypocrite crying fake tears of grief. The expression comes from an ancient anecdote that crocodiles weep in order to lure their prey, or that they cry for the victims they are eating.  

Why we Cry or weep?
Crying is increased lacrimation due to strong emotional stress, suffering, mourning, or physical pain. This practice is not restricted to negative emotions; many people cry when extremely happy. 

Scientific Basis of Crocodile tears syndrome: an uncommon consequence of nerve regeneration subsequent to Bell's palsy or other damage to the facial nerve in which efferent fibers from the superior salivary nucleus become improperly connected to nerve axons projecting to the lacrimal glands (tear ducts), causing one to shed tears (lacrimate) during salivation while smelling foods or eating. Presumably, one would also salivate while crying due to the inverse improper connection of the lacrimal nucleus to the salivary glands, but this would be less noticeable.

Sometimes, if we yawn, our tears fall. It is because of excess tears. Tears are helfpul in washing away dirt in our eyes. That's why tears really help us to avoid damaging our eyes from germs or small particles. Proper care of our eyes are important. We must eat healthy foods and give them relaxation. If you notice symptoms of poor eyesight or any eye problems, better ask one of the professional optometrists. In Indianapolis, my current hometown has a lot of great optometrists Indianapolis-based. You may visit our hometown to find one.
