How Long Do You Keep Your Laptop On?

My laptop isn't administrated on a network that runs night updates, and I don't use it as any type of server, but for some reason I leave it on for days at a time. Okay weeks. Okay it's been like two months.

My SSD makes startup really fast so that's not an issue, and I could easily give my laptop some time off while I'm asleep, but every night I just close it and put it under my pillow. Is this normal behavior? If I clarify that I don't actually sleep with my computer does that change your answer? What's the uptime on your laptop right now? Ruminate below.
