Yep, appointed first aider, doing my refresher course in a few weeks. Very useful skill to have IME, often because it gives you the confidence to act decisively.
Best usage was when 2 handed on a 32ft boat leaving a marina. My dad slipped and headbutted a winch 🙁 Got back into the berth OK but then went into medical shock and lost conciousness whilst leaking plenty of blood Kept calm and dealt with it effectively, which would have been unlikely without training. Priceless knowledge…
