This reminds me of a feature I had enabled on my previous computer but hadn't enabled on my current one yet: having MacOS announce the time on the hour. Sometimes it would scare the crap out of me, but it was effective at breaking me out of the periodic trance state that's so easy to fall into. I think I'll enable that again...
I despise church bells. Hourly is bad enough but every 15 minutes? Imagine if any other entity decided they could just blast their theme song loud enough for the entire town to hear every 15 minutes. There’d be immediate uprising.
I grew up living next to a convent, and the nuns who lived there had a bell that would be rung every hour.
After moving away from that house I would sleep incredibly badly, and I always wondered if I was waking throughout the night "surprised" at the absence of the bell, which I'd otherwise heard every day of my life.
