As a photographer I'm sure the thought of losing your sight must be horrifying. So here's a little inspiration. Amazing teenager Ben Underwood was blind but got around almost as well as sighted people by teaching himself to "echolocate". This video was voted one of the most inspiring on the web on Mashable. NB: Ben sadly passed away earlier this year, but his inspirational story proves that no obstacle is insurmountable. Cheers, Nigel
