Blimey! 15 years old.
You have by now discovered that it is indeed possible for a 15 year old male to not only produce a full basket of dirty laundry per day, but also consume 4lbs of assorted meat, six eggs, five pints of milk and one large family sized cake, in between family meals.
It is purely down to 15 year olds that the farming and confectionery industries thrive.
Well done. Time flies indeed.
