This is how I feel some times as an invalid (or is that invalid as in not valid). I know it is wrong, but if Nietzshe said it, it must have been thought many times before. Just having a bad day, I'll be more up tomorrow.
"The invalid is a parasite on society. In a certain state it is indecent to go on living. To vegetate on in cowardly dependence on physicians and medicaments after the meaning of life, the right to life, has been lost ought to entail the profound contempt of society." -Friedrich Nietzsche - Roger in Kennewick, WA
