The Big Life Fix With Simon Reeve

9PM, BBC2

Following Simon Reeve and his team of designers, engineers and computer programmers as they utilise the latest cutting-edge science and technology to help people in desperate need, this poignant, uplifting series is never less than remarkable. Episode two follows their mission to help Graham, who has been unable to speak since being paralysed by a stroke in 2014. Can the team give him a voice? Plus, they build a bike for teenager Oscar, who was born without hands or feet, and is desperate to cycle like his friends.
