That's exactly why I didn't choose examples like doing nothing, playing sports, going to the gym, games, gardening, etc. I realize "free time" is a nebulous, imprecise term that people have different opinions about. But for me, it's about time without commitments. And of course it's optional! Hell, even the job I need to survive is technically optional: I don't have free time when I'm scheduled to work, but I very easily could, for either my next workday, or longer...
