Scot overcomes temporary paralysis to row for Britain
David Smith was born with a club foot but went on to represent Britain in bobsleigh, karate and rowing.
Then last year, doctors discovered a large tumour embedded in his spine and surgery to remove it led to temporary paralysis.
He has not only now taught himself to walk again but has just been selected to represent Britain in the upcoming World Rowing Championships in Bled, Slovenia.
Here he talks about how he was diagnosed, and how he recovered from life-threatening surgery to row again.
