This is what you
experience when your
head comes into contact with
asphalt at around one metre per second or more (tested upto around 10m/s). On the
surface it sounds like someone knocking together a pair of
claves, but from the
inside it sounds like someone dropping half a
cow onto an upturned, fibre glass
boat. This is usally almost
instantly followed by the
taste of blood and a
smell like someone turning off a
TV.
Generally unpleasant.
