You laugh, I laugh ;d
They laugh, We laugh :D

People say "An apple a day keeps a doctor away"
But for me, you don't need an apple because laughter is the best medicine.

Why?

The mind has an enormous influence over our health.
Doctors' casebook are full of examples of patients whose illness came from general depression.
When a healthy person receives bad news, is understandably upset and before long complains of being 'run down'. One British shows that chronic diseases among the unemployed is six times as high as among those at work.

The body reacts to mental stress by producing more cortisol and adrenaline.
These hormones increase the heart rate and blood pressure, improving our performance so that we can perform more efficiently. Too much stress overstimulates the hormone production, causing us to become less efficient. That is the reason why some people faced with life-threatening crisis find themselves unable to act rationally.

Laughter triggers nerves in the brain to start a chain of reactions. The body's endocrine system secretes natural painkillers and tranquillisers. Other substances aid digestion and the arteries relax to improve the blood flow.

There is no doctor would say that laughter will cure all kinds of diseases, but there is no doubt a laughter does bring us all a power of good.
