I've been meaning to ask someone about the peak flow meter for ages. I've done it twice now, once at my initial Class 1, and once at my last renewal. Both times I haven't quite reached the figure required, or just barely. Both times the doc has said it's OK though. But I've been surprised, as although I'm not super-fit, I'm probably above average...live up one of the steepest hills in North Wales and walk home up it regularly, swim and do salsa and a few other fairly strenuous activities. Does being female and fairly small make a difference, or what? I'm fairly clued-up on most medical matters - especially where they concern me personally - but I don't know about this one.
