I enjoy seeing the occasional selfies posted by friends on FB, but I do think it's unhealthy when someone's primary hobby seems to be taking & posting pictures of herself (Yes, it's usually a her and not a him, although not always). Most of my friends who do this actually have mental health issues of one kind or another.
Alan, anyone can see that taking selfies are not your primary interest in life, so that's not what I'm talking about. You are clearly a person of many activities and interests.
I'm referring more to those shots so often taken in front of the bathroom mirror; you would think someone could at least find a better backdrop!
I think photography can be a wonderful hobby (thinking of you Cathy A!), but a constant series of self-portraits of the photographer just doesn't seem like it would be very gratifying.
