Continued <strong>from</strong> page 37Each year, about 8,500 studentsplay intramural sports, participating ineverything <strong>from</strong> triathlons <strong>to</strong> table tennis.While some <strong>of</strong> the teams play ata varsity level, there are divisions for alltypes and abilities – inner-tube waterpolo, for instance, for students whoneed help staying above the water-line.Anne Richards, one <strong>of</strong> the ninesleepy-looking specta<strong>to</strong>rs in the stands,is here <strong>to</strong> see her son Mark skate forthe engineers. “The teams only playfive games in a semester, so if you missone, you’ve missed a lot <strong>of</strong> the season,”she says. The late start time is finewith Richards: “It’s more convenient,actually,” she says, eyes on the ice.“This way, it doesn’t conflict withanything except sleep.”12:28A.M.Fiona Rankin studies a set <strong>of</strong>graphs scrolling across her computerscreen in the sleep labora<strong>to</strong>ry atthe Toron<strong>to</strong> Rehabilitation Instituteon <strong>University</strong> Avenue.The graphsmeasure the breathing patterns,heart rates and brain waves <strong>of</strong> threepatients. Rankin points <strong>to</strong> a longflat section in one graph.“This manessentially s<strong>to</strong>pped breathing fora full minute,” she says.Rankin, a technician, is workingthree 12-hour shifts this week.Most patients at Sleep ResearchLabora<strong>to</strong>ry have sleep apnea, acondition that can cause them <strong>to</strong>temporarily s<strong>to</strong>p breathing dozens<strong>of</strong> times a night.
