Thanks for the replies guys - sounds like I've booked the right thing!
I'm sure I read in another thread somewhere that occasionally they make you run round the car park before doing the peak flow tests....
Sounds like I should get the bus from the airport - I'll just have to kill the time shopping for new sunglasses.
I got my optician to check my eyesight against the class 1 standards. He checked the colour vision and muscle imbalance and whatnot as well so hopefully I should be fine. I wear soft contact lenses - the caa website says hard ones shouldn't be worn on the day of the medical, can I wear soft ones? I do have glasses but I rarely wear them out in public!
I clean my ears everyday with a cotton bud but I guess this doesn't get right inside... can you buy drops over the counter/ off the shelf? I sometimes wonder if my hearing is all it should be
