Why is the shell important to a life cycle of a chicken?

Cause when the weightlifter does the bench press exercise, it is very important to go as deep as possible without compromising the form of the lift or causing injury during the vital points of the lift. If a bench press is done on the smith machine by a group of 3 scrawny males who think they are ronnie coleman by bench pressing 35kg( i know, lightweight right) but only lowering the bar a couple of inches, please just slap them beta faggits and ask them to leave the gym as they are wasting another more serious weightlifters time who may wish to use the smith machine. Just to point out i have no clue about the shell being important but eggs are tasty and have 8 grams of protein per egg, FUARRRK
