don't worry...

There are only 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 only two things to worry about,
either you will get well or you will die.
If you get well, then there is nothing to worry about.
But if you die, then there are only two things to worry about,
either you go up or you go down.
If you go up then there is nothing to worry about.
But if you go down you will be so busy shaking hands with your friends
you won't have any time to worry :)
