From what I’ve heard it is actually hard to fall asleep after an extended time of being awake. I doubt the one mechanism discussed here is enough to explain all that is going on while sleep deprived.

I think it is fine but we also need lessons to properly interact with the technology. Scams, fraud, disinformation and checking sources were handled very abstractly at best and archaic at worst.

I’d say so yeah. I switched between headphones a lot recently and they don’t stand out. All headphones have their own sound anyway. I just embrace what they highlight and get to know my favourite songs again.

I’ve found that bone conducting headphones work well for this. They are even secure enough for running and climbing.
