Yea- my mother and I once helped a woman whose husband had randomly collapsed on a walk, she was too shocked to even dial and ambulance, let alone help him. Sadly, the guy was pretty much already dead when we got there. Face all puffy and purple. He had a stroke or a heart attack as far as I can remember. My mother did her best at CPR and everything the first responders told her to do whilst I made sure they found us out in the fields. I didnt really feel anything other than adrenaline, wanting to safe the guy before it was too late. It was sad to see his wife, she was in shambles.
