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