Let's to laugh. Laughter prolongs the life. 
This is my first joke here:
A little girl and boy are fighting about the differences between the sexes, and which one is better. Finally the boy drops his pants and says: Here?s something I have that you?ll never have. The little girl is pretty upset by this since it is clearly true and runs home crying. A while later, she comes running back with a smile on her face. She drops her pants and says: My mommy says that with one of these I can have as many of those as I want!
