Optimism

A very interesting observation about aircrew and frequent fliers,is that they/we experience our days very differently from more earthbound people when it comes to the concept of day and night,sunrise and sunset.
For instance,after 9years of long haul flying,I don't think and feel the same way as I did before I started flying as a career.You come to realise that the sun never sets,it's always shining.Therefore your levels of trust and optimism rise accordingly.(see previous post)
