Flying for some is like a drug they can't give up and even after retiring they travel the same routes, stay in the same hotels, can't seem to shake of the "Good morning Captain jock strap" at the hotel reception.. plan to give up at 60 and start a hobby or part time job plan 5 years before, enjoy your life and get out of the rut! If I could afford it I would give up today after 23 years of stomach gas,haemorrhoids, sleepless nights.. would I want a 70 year old surgeon? perhaps as a consultant but not holding the control of the knife!
