But comfort areas are hugely different.. I prefer the range from scolding hot to ice-cold (I start my shower in the middle area, then prefer to turn up gradually as I get used to it until it's very hot (so hot I'd feel uncomfortable if I started at this temperature), then after a while I get very warmed through, and I turn straight to the coldest setting and enjoy the constrast from burning hot to burning cold, and that's the perfect finish for my shower. Then I step out of the ice cold shower and enjoy the warm air against my skin (even if that warm air is about 19.5C at the moment, it still feels warm in contrast to the ~2C water)
