The good people at Buzzfeed have put together a list of 18 Things You've Been Doing Wrong Your Whole Life.

Now I'm not ashamed to admit that I've been doing lots of things wrong my whole life. Just ask me about my real estate dealings. But I'll start with the things on this list that I knew already: 6, 13, 14: Eating Tic-Tacs, taking the phone to the beach, and sharpening razor blades.

But I had no idea I was cutting cake wrong.

Nor did I know 3, 8, or 11.

And I will have to try #10, although I don't know how others will take to the idea.
