Lup, if you'd care to read my profile you will see that there is no raw nerve to hit. I have a PPL and I do not have an instructor's rating.
However, it's just that your advice seems to contradict what so many others have said (over the years) on here with respect to age vs employability. I was curious as to why when it doesn't seem to have been a factor in many other people's choice of career switch.
Cheers
