 PS

As a practicing surgeon in Sri Lanka, I have gained an impression that there was a high incidence of cancer of the oesophagus among the tea estate workers, in central Sri Lanka. Anaemia and avitaminosis will also play a large part in contributing to the disease among these workers, but they also have this habit of drinking frequent quantities of boiling hot tea with no milk, while on the field.
