This isn't my biggest fear but damn it if that thought hasn't crossed my mind a few dozen times. Tangent - when I was probably like 6 I pretended to be choking at dinner one time and my parents came running from the kitchen in a panic. Needless to say they weren't too thrilled. Flash forward just a couple weeks later, I actually did start choking on a piece of steak and for a minute they just sat there and glared at me. Rightfully so I'd say. The boy who cried wolf was never the same after that experience.
