The race, at various times, had seven different drivers in the lead.
The record is Monza in 1971 when they had eight.
I read that the average age for drivers at the 2013 Australian Grand
Prix was 27 years and 61 days - apparently the youngest starting
grid ever.
Mind you I have this theory that each lap in one of those cars during a race
probably ages the driver by another day.
By the end of the race
it means you probably have aged by a couple of months. This clearly
disobeys what we know from the theory of relativity.
