I had my first kidney stone at 18. Mine was made of calcium. My doctor asked how often I drank energy drinks and how much spinach I ate. I said a lot of both and he said pump the breaks. I stopped with the Rockstars but kept the spinach because it was obviously the energy drinks because they're so bad for you. Four years later I'm getting surgery for my third stone. Guess who doesn't eat spinach (or Tums) now?

Not medical advice. There's a variety of stone types and innumerable causes that are poorly understood. Comics and memes are also not medical advice.
