@ForFunAquaTurtle Just a couple I'm thinking of...
Lying out in the sun on sunny days. It is not possible to sleep with the sun in your face, and lying in the sun literally serves no purpose.
Using a phone for all day to day digital tasks, when a standard desktop computer is much faster and more proficient for completing those same tasks.
Seeing housing as an investment, rather than a functional place to live.
Idling an engine outside a shop. Why? This has a negative impact on the car, and also harms people's health, so it's not clear why people do this.
Driving a car that is much bigger than it needs to be. Again, why?
