Gosh, in my day proto-programmers would quibble those facts:
"But I never drink water, only Jolt cola, yet I'm still alive!"
"But I wager that I can go longer than 7 days with water - Soup is a food, so food alone it is for me"
"Is an ice cube food or water - it is after all a solid", quickly followed with "well, I'ld like to see you last longer than 7 days on just steam".
"Can I drink from the dehumidifier i my room? Can I use evaporation to purify my urine?"
"what do you mean 'and' in 'without water in 7 days, and without food in 14 days? Don't you mean or? After all you can only die once"
"Sorry Dad, I've learnt how to pick locks at the geek club - do you want me to show you?"
"But If you eat a lot of fruit and vegetables, you can replace lost moisture from just your food alone, and never need to drink"
