Calyx seems to be the best option for you. https://calyxos.org/ Next time you buy a phone (and live in the EU), you may consider Volla. It’s degoogled Android by default and dual-bootable with an SD card, so yo can try other OSes while keeping your daily driver.

Andromeda Linux around 2009. It had cool astronomy based theme and animation.

Thick (~1m) mudbrick walls. I lived in a house like that for 2 years, it felt cold inside in summer.

Yup. I’ve been listening to ‘You shouldn’t be an astronomer, you can’t make money as one’. Now I work at the state railways, I constantly have myself sent to school like driving a maintenance engine. You guessed right right I also got the ‘don’t work at the railways’. There’s not much of my family I contact these days.
