The elimination comes *after* the year, naturally.
The need to eat: What's the last thing you ate? That specific thing is now the only thing your body will be able to process for a year. McDonalds french fries? You can't have any other fries. Mum's spaghetti? Better hire her as a full-time worker to make you spaghetti for a while.
The need to drink: Your body can only process tap water for a year. You cannot drink from the same tap twice in the same day.
The need to sleep: Until this time next year, you will only be able to sleep 8 hours total per week. It's probably more than some people here already get, ironically.
Just fun little shower thoughts I had. ^^
