You did not ask.
Why would I watch television, watch a movie, drink coffee, smoke a cigar, take a drive in the country, sip a nice ale, play a game of cards, watch fireworks, see a play, photograph wildlife, etc, etc, etc?
I enjoy the experience of it.
Some things are enjoyable, others are just fun, but unhealthy and actually filthy for our bodies. Like cigars and smoking pot. You can excuse it away all you like, but my point still stands....inner happiness precludes the need for many substances. Of course we can still enjoy certain pleasures, but not ones that are obviously really harming our bodies and souls.
