When I did my first aid training they explained that the deeper layers of the skin were still burning if you don’t cool the burn long enough so in order for the cold water to be effective, you need to cool it down for ages. Maybe not 30 minutes, although it depends on the severity of the burn.
I actually put that to the test, I kind of burn myself regularly cause I’m a clumsy oaf. One time I put my wrist under cold running water for 10 mins, and there was no blister in sight the next day!
Superb interview! I had boulder dash on the nes as a kid, I loved playing it but never made it past the 2nd world
