your body knows best

There are many situations where your body knows best:

1. Don't eat that extra slice of pizza
2. Getting up for the 8am Saturday yoga class just may kill you
3. Get off the train or the smell of piss will turn your gag into a vomit.

Also, when you get in the elevator at 11am, meaning to go only to the 28th floor, but you actually push the Lobby button - your body knows best. It knows you should just leave. Or, at least it knew that you needed to take a ride in an elevator...
