Sometimes I miss restaurant work. I sit in front of a computer all day in a quiet room, it's so completely different to be on a line at a busy restaurant. It's loud and dangerous and hot and chaotic. In many ways it's the opposite of being a sysadmin. I'm not sure my body could take that kind of work now, but I do think about trying it again from time to time.
I do like the concept of having Mise for us "knowledge workers" too.
I worked in kitchens and as a server pretty regularly from about ages 16 to 22. After several back-to-back busy shifts my joints would hurt until I got a day off. Even at 36 now as I start to feel stuff ache a little more often and a little more acutely, it was different then. It's easy to see how decades of that kind of work can really take a toll on your body.
I was a sysadmin for an on-site HPC cluster and this sounds familiar. Compared to a restaurant, it's probably less dangerous and chaotic but more loud and hot.
