What a good topic!
When I was in my twenties I was unworried and didn't think anything could happen to me, my friends or family members.
But then during a futsal match one of the guys collapsed and I just stood there not knowing what to do.
Luckily there were others that did.
That incident made me think; what if I was alone with someone?
I have subscribed to a first aid course after that to learn how to help in case of an emergency. I also learned how to perform CPR, use an AED and what to do when someone has severe wounds or burns.
I think everyone should be able to perform CPR and how to use an AED.
About the med kits; I have a fee. In my car, in my home and a small one for traveling which I carry in my cycling backpack. I do need to check up on the dates of the stuff that's in it though.
