On 2nd May 2015, I'm going to be joining the Traveleyes Team and abseiling down the front of the Royal Armouries dressed as a superhero, in aid of raising funds for Sightsavers.

Sightsavers is an international charity working to eliminate avoidable blindness and support people who are irreversibly blind to live independently. There are 39 million blind people in the world, but 80% of blindness could be prevented or cured. That's 31.2 million people who are blind when it could have been avoided.

Shocked at how unfair this is? So am I.
