I might be wrong, but i think the "why doesnt he get a job as a paramedic, midwife etc" comment was a touch of sarcasm from the poster, rather than serious question, based on the long thread conversations where we hear about all the hundreds of highly qualified BA CC who are lawyers, doctors, teachers, dentists, midwives, who decided to give it up and be CC instead.
(Not that i doubt that there are indeed some former professionals amongst the crew...)
