Sorry, medicine and aviation are different. That is not to say you dont need to concentrate in the NHS but it is totally different work, mostly done in one time zone, on static or regularly rotating rostas indoors on the ground. Fatigue does play a role in safety in both industries, but whereas pilots are restricted well below the european working time directive, doctors are actually exempt. Doctors work single handed - no multi crewing which is a very good idea as we have no CRM training! I worked 112 hour weeks for many years in medicine and it was far far easier than flying within EASA limits.
