I’ve treated some pretty nasty first aid incidents (first responder for crashes on the A9 for example), my worst until recently was a lady having a stroke in front of her daughter and grandkids in the middle of a busy restaurant.
However, that pales into insignificance to watching my girlfriends daughter choking on her food. Scary for everyone and thankfully I just went into autopilot and cleared the blockage.
Basic first aid is a very easy course and it can be the difference between life and death. If you can do one then please do.
