Why worry?
There are two things to worry about:
Either you are well or you are sick.
If you are well, then there is nothing to worry about.
But if you are sick, there are two things to worry about;
Either you will get well, or you will die.
If you get well, there is nothing to worry about.
If you die, there are only two things to worry about;
Either yo will go to Heaven or Hell.
If you go to Heaven, there is nothing to worry about.
But if you go to Hell, you'll be so busy shaking hands with friends,
You won't have time to worry.
