When you’re suffering from a calamity such as a snake bite, you need to be technically correct. Will that get you the help you need? Apparently not. Where is First Aid Man or Ambulance Man when you need them? This comic is by Enzo of Cheer Up, Emo Kid. -via Geeks Are Sexy
No they aren't. The ostriches may have been healthy, back before you turned them into burgers, but that doesn't affect me in any way.
If you meant "Eating ostrich burgers will make you healthy" the word to describe that is "healthFUL". e.g: "Vegetables are healthful." Nothing dead can ever be "healthy."
It's not some long-lost word, it's just plain incorrect conjugation... Like someone saying "You're very beauty."
