There is such a thing as the HAPIfork which measures: How long it took to eat your meal, the amount of fork servings taken per minute and the intervals between fork servings.
In other words your fork will be watching how fast you eat. And probably since it then works with bluetooth and sends all this data to your phone or somewhere else, you'll be getting berated about your eating habits. Do you want to know if you eat too fast? Do you care? Well, this fork may be for you.
You can get it at Amazon which sells it through Brookstone which means you could go to Brookstone. 99.99.
