Art has a therapeutic effect on one's life; I was once a pretty good duck carver and painter. Even though I haven't carved a duck since 86 (I got into bow making) I kept a couple of decoy blanks and all of my carving tools for the day I am too old and infirm to make or shoot bows anymore.
I even got into doing Bob Ross type paintings years ago, of course I threw them all away and never showed them to anyone because they were somewhat mediocre but I enjoyed painting them.
I live alone as well, at almost 76 most of my close friends have either died or moved on. The Beatles song "Eleanor Rigby" makes more sense to me now.
