I've often thought that rather than showing beautiful Apple people buying organic food from very middle class shops, they should, next keynote, have an alliance with KFC and show how family sized buckets can be purchased with just one click with the new Apple/KFC app. Then the watch could link in to show how much saturated fat you have consumed and how close to that heart attack you are. Be good to have the gimmicky sensors used for once!My favorite workout is shoveling food into my mouth
Also if you fall over whilst waddling to the toilet, your watch could sense this, and determine when your KFC cools down to make it unpleasant to eat and thus automatically order you another!
