His wheezing of late has been more pronounced. Either he's making some underhand statement about the continued need for tobacco money in F1 or his remarkable resiliance in the face of neck-down paralysis is finally melting.   I remember a medically minded friend commenting when quadraplegic Curtis Mayfield made his last album that it'd better be good cos there wouldn't be another. Would those with more medical knowledge than me care to comment on long term survival for those injured to this extent?
