To 1Gear.
Do you listen to music?
Do you wear clothes that look 'smart', 'trendy', 'cool'?
Do you go to the movies?
All of those things are 'art', 'design' and 'craft'. Appreciating and enjoying them is part of what makes us human.
You seem to think these things are pointless. I suggest then, for 3 months you try never watching a movie, reading a book or looking at a photograph or painting. You are not allowed to wear anything other than mechanic's overalls and an old sweater if it's cold. No jewellery allowed. You are not allowed to eat out or have anything other than boiled potatoes with beans, and can only drink tap water in case your senses are stimulated by food. No sex either, btw, because that can be about appreciating the aesthetics of someone.
No riding a bike. In the evenings, sit and contemplate nothing. No building snowmen or sledding. No playing either.
In 3 months time, come back and talk to us about it.
