No matter how we argue in comfortable air conditioned lecture halls about global warming and climate change, we will still be able to fry eggs on the bleachers while teenagers eager to make the grade as college football players have two-a-day summer work outs. So it was on September 24, 2006, when Dale Lloyd II collapsed after sprinting 100 yards for the 16thconsecutive time during a conditioning workout. He was a freshman cornerback for Rice University. He died the next day. His death was linked to a trait for sickle cell anemia (a blood disease adversely affecting the red blood cells where sickle cells can block the flow of blood through the vessels).
