Andrew: Back at the beginning, I thought my life would be over. I thought: this is not going to be possible. But it is possible. I’ve got a good job, travel a lot, go on holidays, etc., and I feel I am very lucky and fortunate with what I do have. I think you have got to look at things differently, and you have got to stop being defeatist – thinking that you can’t do things. But, just as important, you should do the right research because you don’t want to go out there and fall over on the street.
