i say why not drink,smoke or get addicted to drugs, when one knows d consequences!!!! esp by a doctor him/herself.if anyone who has been trusted by d pple to save their lives during illness wants to destroy oneself,then why do others bother????
stress due to studies??? common if a doctor cannot learn to handle one's own stress then how will he console a patient during acute illness??
but thats very personal view.no offence to anyone.
