THE 8-HOUR STUDY DAY IS COPE.

Somewhere in your group chat, right now, someone is typing "studied 8 hours today, absolutely cooked". Everyone replies with the fire emoji. Someone else quietly panics because they only did four. And the whole chat gets a little bit dumber.

This is Lesson 8, and the title is the whole thesis. The person quoting hours at you is measuring the wrong thing and bragging about it. Hours are an input. Nobody scales your chair time. There's no box on the exam paper where you write down how long you sat at a desk.

Inside: the subtitles for what "I studied 8 hours" actually means, the one unit that's worth counting instead, why the hour-counting arms race exists at all, and a safety clause your parents will want to frame. Fair warning: the translation table is going to feel personal.
