Im Dong Hyun

As if it weren't hard enough to shoot at a target 70m away with a bow that weighs close to 15 kgs, this South Korean Olympian archer does it despite being legally blind! The 26-year-old somehow aims despite his obvious handicap.

Believe it or not, this incredible man is the second-ranked archer in the world and has two gold and one bronze (at the London Games) medals to his name!
