Address grouses faced by housemen

I REFER to “Trauma faced by some housemen in hospitals” (The Star, Dec 8 ) and “Train housemen in a more humane way” (The Star, Dec 13) and have gained valuable insights into the medical profession.

Why the long working hours? Is there a lack of housemen, Medical Officers or specialists in the training hospital? Tired minds will surely make mistakes. I am sure patients would dread to be treated by half-awake doctors.
