I often find myself reading lists about such things, but ultimately come away thinking they're subjective, such as interminable compilations of of places/ books/films etc., which must be read before you die. Really! my thoughts are maybe your definitive list, of the person that compiled it, but not necessarily mine. We're all individual enough to know what we like and don't like. Recommendations are good, but once those meander into the realms of you really must........I'm inclined to feel there's
no must about it, just shove your list!
Not cool "killing children" that's a bloody understatement, it's wicked. Wicked is a definite understanding of something really wrong. Love is too important to be described as cool, it, is for the overwhelming majority, an innate part of the human condition, so describing it as cool just sounds facile. The ills of the world, so many, cannot be alluded to as "not cool" that's just too fatuous for words.
Cool is a concept. Right now, well if the younger generation of our family is anything to go by, they regard "mid century furniture as cool" that's 1950/60s to us. Yeah it's ok, but we remember it from the first time around. Every generation has their "cool" often It's whatever is on trend. My cool growing up were mini skirts and hipster bell bottoms, my teenage granddaughter's is low slung baggy jeans/track bottoms showing way too much midriff what do I know, me and mine showed way too much leg. My cool music was rock, my kids, probably some of that, but drum and base emerged as their definitive cool.
I don't really look to celebs as being cool anymore, well put it this way imo the really cool ones are those who have the mystique, in other words the less we hear from them the cooler they are I don't care about your bloody politics, your nepo kids, just do what you do, act, sing, make your runny jam if you must then shut up and go away!
Cats are cool imo, they are the coolest species to walk the face of the earth, but some misguided people would say dogs are cooler, they're wrong it's there it's in the alliteration "Cool Cats"
