How old is Biff?

[Howie Feltersnatch]

I walked 6 miles to school uphill both ways in 4 feet of snow when 6 miles was 6 miles and not a two house walk to a bus stop.

Lets see.....in 1935 they changed the standard 'mile' to a 'lazy mile' in which 2 houses can snugly fit....so if Biff was still walking to school he has to be atleast 60 but maybe as old as 78...

what?

thanks for the bump
