Let's clear this little thing up, as I heard it again today - somebody claiming men have one less of rib (I assume they mean a pair) than women.

This is false, we both have 12 pairs of ribs.

This myth is probably even more widespread than the 10% of our brain nonsense - the same nonsense that is used to claim the existence of whatever paranormal ability anybody cares to come up with.

Today, unlike people back in the dark ages, we don't just guess at how many legs, teeth or ribs something has. We do some science, and do an experiment - like counting whatever it is we're claiming something to have or not have.
