To quote Pukin Dog
'Like Seat 0A points out, would you let your loved one or yourself go under the knife of a surgeon who shows up to work on you 3 or 4 times the legal alcohol limit of what his profession allows to the point he'd be arrested for drunk driving? The anesthesiologist? Are you going to care that he's sad because his dog died or his wife left him? Get a grip kiddo.
In fact in the USA 195,000 people every year are killed by medical error. Far more than those killed by drunk pilots. The person most likely to kill you in the USA is a doctor.
Pilots are monitored to the extreme - who is monitoring the doctors and how far advanced is medical CRM compared to aviation CRM? I suspect not very far.
