What "laugh' can do to us?

Happy! avoid from having stress or release the burden of work.Manage to proceed or at least with great pleasure without tense.Let me share with you some jokes what might make you happy.
Why I  choose my career?
Would you like to continue your father's career as an eye specialist?
No!
Why?
My  father unable to make much money
Why not?
A person only got 2 eyes,so nothing much to do with them.
So what would you like to be
I would like to be a doctor also only in different specialization
What then?
I would like to be a dentist
why ?
Each person got 32 teeth, so I might be richer than my father.

So each person got jokes to tell, proceed with it as long as you're not hurting other.To make people happy is a very sincere thought.
