I'm conscious I have to types of play though, I'm fully conscious sometimes play can be about learning and training, it's why I ski more difficult terrain than I'm comfortable with, but then I might go eat a massive bowl of pasta and have a glass or three of wine. On an intellectual level, I know there are healthy more rewarding things to eat. I know wine isn't great for me at those quantities. But I consciously make the choice to do it because it's fun.
I don't think that many calls indulging in food or bodily needs "play". Those are just core rewards, play is an active activity that is fun without being directly related to your survival, like eating is.
Eating ice cream instead of stale bread is absolutely play, just like running around on a soccer field is play even though running is a survival skill.
