William Reed is a bodybuilder, and he's also colorblind. For his 66th birthday, his family all chipped in and got him a pair of Enchroma glasses that help a colorblind person to see colors. Reed suddenly sees the world as it is for the first time in his life. Yeah, it takes him some time to open the gift, so if you can't wait, skip ahead to 2:00.
His joy is hard to see under the dark glasses …until he starts sniffing. It's a change we can't imagine unless we've been in his shoes. Reed says the colors make everything look 3D, so being able to see colors as others do must make a difference in depth perception, too. -via Digg
