Unrelated to the question, but what sort of degreesvare you eating celery in? Celsius, where the celery is quite cold, Fahrenheit, where the celery is frozen solid (unlikely). I highly doubt one can eat celery at 7K.

Or maybe it’s latitude, where you only eat celery when you are close to the equator (north or south?), or longitude, when you are 7 degrees west or eat of the Prime Meridian?

Maybe the angle of approach of the celery should be 7 degrees from a perpendicular line extending from your mouth? Or perhaps the angle from a line parallel to your arm?

This is what happens when you do not leave in units. Remember your units, kids!
