What are people who work 80 hours a week actually doing?

Apparently nearly every engineer at Tesla works this much even interns. But that’s 16 hours of work a day. When tf do you relax cuz you have 8 hours to commute, eat dinner, take a shower, sleep, etc…

In a normal relaxed job let’s say you have 20 hours of real work a week outside meetings. At 80 hour work weeks you basically doing week worth of work in like 2 days. But then what exactly are you doing next for rest of the week? what kind of tasks are you actually doing? How do you not burn out after like 3 weeks if you are working that long each week? I have so many questions.
