A woman goes to the doctor to get some medication for her elderly husband. She's given some pills and is told that he should take two every Sunday, Tuesday and Wednesday and skip the remaining days in the week. A month later the woman returns to the doctor to tell that her husband has died of a heart attack. 'I don't understand it,' says the doctor. 'His heart hasn't bothered him before. I hope it wasn't a side effect of the medication.' 'Oh no,' replies the wife. 'The pills did him good, it was the skipping that killed him.'
