Thank you all for your replies, they make very interesting reading. Certainly more interesting than "advanced clinical physiology".
I don't see myself as giving up per se, more changed direction. I still fly, but it's a hobby not a job. Maybe that's why it still gives me a thrill. And my day job ain't that bad either. I don't have much to complain about really.
Oh, and BritishGuy, if you're really interested, then the website to go to is:

Ta Ta people, and thanks again for listening,
