If I tried to bike during commercials, I'm afraid I would spill my wine.
LOL! You just need to drink it through one of those caps with the long straws attached...
Seriously, though, I'd differentiate between habits and hobbies, when it comes to how I spend my time. To keep it simple, I count as "hobbies" anything that is done for the sake of learning or personal growth.
For instance, I like to walk on the Sunabe seawall at sunset, looking out over the East China Sea, which is simply wonderful. But that's a habit, not a hobby. I know how to walk, I know what a sunset looks like. I know what the waves sound like as they crash against the sea jacks. I enjoy this activity immensely (so long as the mosquitos leave me alone), but I don't actually engage in it in order to grow.
I think the same is true of most TV watching... but as a medium of communication it can assist in other hobbies. For instance, if astronomy were one of my hobbies, I might watch every show geared towards astronomy, and that would certainly be related to my hobby. But the hobby would have nothing to do with watching TV.
This isn't to say that all habits are bad, but just to draw a useful distinction. I probably enjoy a nice glass of wine as much as strongjen, but I know next to nothing
about good wine. There are some people--for whom wine is a serious hobby--who would look down their noses at what I drink as so much swill
. That's fine. I'll be the first to admit that they are right, and I am wrong. After all, it's their hobby, not mine.
I do the opposite, when it comes to coffee. People rave about Starbucks (for example), and I want to say, "How can you drink that burnt swill? It has completely lost its origin!" But that's because it's my hobby, not theirs.
For me, it all comes down to a single category: education. If I'm engaged in an activity to learn more about it (i.e., further my growth in that area), then it's a hobby. If it doesn't meet this simple criterion, it's a habit.
With this in mind, I'd revise my earlier list, and add "writing" to the list of hobbies, and remove "chess." In the past year, I've decided to stop studying chess, and simply play for fun. I enjoy it, and do it regularly, but it's strictly a habit now, not a hobby.
