I hope I did not infer that I was intending to 'fudge' the medical, in fact I would hope that is not even possible!
I do however intend to give myself the best possible chance by doing a bit of exercise beforehand, just for a mental boost more than anything probably.
Thanks very much for the link, its a bit heavy going but interesting anyhow. Will have a good read tommorow when I am feeling perticularly nervous...just to 'chill-out'.
Crossed fingers and thanks too both responders!
