After attaining a Ph.D.Degree,one is supposed to be equipped to have a most rational and scientific outlook of the processes and events in general,not restricted to his field of enquiry alone when he was pursuing the Degree.This ability matures with age and sharpens with experience.A doctor in Philosophy is always a doctor.His expiry date is the date he breaths his last.Anyway,the suggestion may work well in some other vocations.
