35 yrs ago I had 3 brain tumours. Hospital removed one and sent me to Christies Cancer Hospital for radiation for other two. Later I qualified as a Physics Teacher but then my wife of 24 years left me and has remarried.  Now, over the last 3 yrs I have had dizzy spells and falls, and walk very slowly. I have recently purchased a disability scooter and a self-propelled wheel-chair which I have yet to get used to..
