Lots to think about, however I think I've made up my mind, but any further advice is really appreciated.
It all hinges on the medical, I'm going to have a medical locally here in Canada and then (if/when I pass that!) I'm going to go home to the UK and have another there (I plan to put all my cards on the table and hide nothing) and hope to also undertake the aptitude testing. Any contacts?
As I mentioned before, a life of regrets is not worth living, sometimes you just have to take a chance.
Thanks for all your help.
