Incidentally, our swim team had the highest grades in the school. And for two years running our school had the highest SAT scores in the state. We won state championship too.
I was thinking the same thing. I rode my bike to school before the sun was up for workouts.
In 1972 our sophomore basketball team had practice at 7:00 AM. The gym was cold and the basketballs felt like rocks but it didnt kill us.
