Common Household Hint:
Beware of dead fish; they still can fight back: Do not stab yourself on the dorsal-fin spines of a red snapper fish. If you stab said spine on, for instance, your finger, then your finger will swell and hurt like the dickens. Try to find out before, not after, you prepare the fish, that the spines contain a toxin.
I hope that I will be able to play the piano again someday (sob).
