I read this in a bio of Bentley:
Born in Jonesboro and raised in Little Rock, this self-called "pretty boy" participated in sports in an effort to counteract the teasing and abuse he faced from his classmates over his countenance.
and for Heath:
At Guildford, where most of the sons of Western Australia's farmers were boarders, Ledger was something of a maverick. Disturbed by the school's military aspects where cadets would be trained in the use of weaponry, he instead opted for sports, playing cricket and Rules football and especially excelling in field hockey, making the school's First XI at a very young age.
I wonder if that is what he was referring to? Turning to sports while in school to escape from other pressures?
