Either you are well or you are sick

 

Either you are well or you are sick.

If you are well, there's nothing to worry about.

If you are sick, there are only two things to worry about.

Either you will get well, or you will die.

If you get well, there's nothing to worry about.

But if you die, there are only two things to worry about.

Either you will go to heaven or hell.

If you go to heaven, there's 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.
