Surely your friend with your advice will wake up a little bit and will not die anymore... But you leave some good questions to which you give answers in turn, such as where the first aid kit is used or for whom it is intended. It's interesting to analyse these things.
I like to be prepared and I have a first aid kit at home, especially for simple wounds, but I have expanded it for example for deeper cuts because my brother works in a restaurant and uses an axe... he has been hurt a few times and I want to have everything I need. If I can help before the ambulance arrives, I don't hesitate to do so.
