It was the 20th anniversary of the breaking of the Berlin Wall recently and what it brought memories of, to me, was of the fact that it's been 20 years since my son had his spinal operation the National hospital for Neurology in Queens Square in London. He was in the hospital after his surgery and he saw it on the TV in his ward and told us about it , when we went to visit. He was 16 then. He and all of us have come a long way and I am so grateful for all the good things that have happened to him and to all of us, in the last 20 years.
