Why Are Average People Overweight?
Bob is an average person:
Bob's height equals the average height in the population, and Bob's weight
equals the average weight in the population.
So why is Bob considered to be overweight?
Notes
- This is a puzzle, not a joke.
- "Overweight" is meant relative to the population.
- It does not depend on the distribution.
