Not to say it's a great use of your time, but watching YouTube videos is a fairly passive activity. You can do it when you're otherwise out of energy and barely able to pay attention, so it isn't necessarily competing with blocks of time in which you can do something like code up side projects and learn to play new instruments. Also, again maybe not for you, but a lot of people's numbers if they're just looking at watch history are going to be totally out of whack if they're using YouTube as a music streaming service. My wife's account is the one logged into our television and this would constitute the vast bulk of watch hours, having music on in the background while cleaning the house, cooking dinner, and doing a whole lot of other things. You definitely can't practice tuba in the background while also cooking and cleaning.
