Sayings for Surgeons

Another incident related by Dr.Mark Amerasinghe, Orthopaedic Surgeon.
In the days of steam-ship travel to UK, Liverpool was the first port of call. Quite a lot of the Medical Post-Graduate trainees trained in and around Liverpool.
Lord Cohen of Birkenhead was Professor of Medicine at Liverpool. Once at a lecture which Dr.Amerasinghe attended Lord Cohen wrote on the blackboard in large letters the following message:-
'Feasibility of an operation, is no indication for it'.
