Americans' Heads Getting Bigger
« on: June 18, 2012, 08:18:14 AM »
New measurements of hundreds of skulls of white Americans born between 1825 and 1985 suggest that their typical noggin height has grown by about a third of an inch (eight millimeters).

It may not sound like much, but the growth translates to roughly a tennis ball's worth of new brain room.
