Rin Kinoshita is a 20-year-old who competes in what many consider the most intimidating Winter Olympic sport — skeleton.
Athletes in the sliding sport take a running start and launch themselves headfirst down an ice downhill track on what is little more than a torso-sized tray. Only two thin rail-like runners keep the sled heading in the right direction.
With their chins mere centimeters off the ground, competitors reach speeds over 130 kph while shooting meters high around steeply banked curves. Racers steer with only the slightest shifting of weight, using their shoulders and knees.
