About 5 years ago I did a biker down 1st aid course with Wiltshire air ambulance, today it paid out.

I was 5 mins from home, driving along in my car, middle of no where and suddenly Im confronted with an unconscious biker on the road and the bike in a hedge.
Im pleased to say what I learnt (and thought Id forgot) was instantly the only thing in my mind, the brain is amazing. Not entirely sure what happened but theres a lot of odd things, the header pipes were cold, she was heavily unconscious but already in the recovery position when I got to her and the bikes ignition turned of with the keys removed but thats all for the police to work out, the important thing is when she was put in the ambulance she was breathing.

Do the course, its worth the time.
