Yes but I think we are just now reaching a critical mass of people for whom it is over but wasn’t for their parents. I believe that’s the most important part, it’s easy to accept that other people are just worse off than you. It’s a lot harder for people to accept being worse off than their parents.

Most reputable sources will specifically say “not cold”. Both first aid trainings I have taken have outlined specific cases where starting with warm and then moving slowly to cool water will help prevent blisters.

YMMV.

Depending on the severity and type of the burn, and the amount of time that has passed (ideally none), actually yes you would.

Cold water is the opposite of what you want to put on a burn. Blisters are a reaction to the rapid change in temperature not the heat.

Apparently In is. I’m not sure who that is though.
