I wish I had more in the way of hobbies. I have to admit that I am jealous of my wife and her passion for her quilting work. She can't wait to get into her workroom most days to work on one or another of the beautiful quilts she creates. My only passion, if I can call it that, is motorcyling. I switched from two wheels to three a few years back, but in the 12 years that I have been retired that is my major pastime. When winter comes, I do find that I get bored and end up watching TV more than I think is healthy. I also walk my two dogs for about an hour most every morning. They need the exercize and I guess I do as well.
Another activity that I have, but it can't be called a hobby, is my being a volunteer with a local non-profit hospice organization. A am a "veteran volunteer" where I have (right now) three fellow military veterans that I visit regularly, who all are in the dying process. Only one of the three is older than me, which makes me feel grateful to be as old as I am and still in relatively good health.
Despite the daily dog walking, the hospice visits, and riding my motorcycle I still have a lot of time to fill. Some days I just end up puttering around, like re-organizing the stuff in the garage. Maybe the key to happiness is really what James Taylor says in one of his songs, that the secret to life is to enjoy the passage of time I try to do that, but the reality of knowing that its not likely that I have that much time left makes me wish I had the desire to do something more meaningful.
