I'd love to see him run a 600m indoors and an 800m outdoors. He wouldn't even need a pacer for the latter, because I'm betting he'd go out very fast.
As for Schultzie, the White Supremacist above, high school sophomores usually turn 16 in the spring/summer at the end of their sophomore year, while high school juniors usually turn 17 in the spring/summer at the end of their junior year. High school seniors, obviously, usually turn 18 in the spring/summer at the end of their senior year. Nowadays, however, there is an increasing number of boys who are held back one year before entering kindergarten (that is, they enter at 6, rather than 5) to insure their readiness and to help them be dominant in high school and get scholarships.
