A guy I used to know, who was a pretty good writer but needed a day job was posing for the life drawing class at RISD.

“It’s the essence of job,” he said.
“You go to work, you plant yourself there and stay for a number of hours. Afterwards you get paid for the number of hours you were there.”

There’s something to that, although there are many people planted in cubicles who are less aesthetically pleasing than a model striking a pose. And whose work does not advance a great cause, such as art, and making sure youth do not draw people looking lumpy and ill-proportioned (unless they are doing it on purpose of course.)
