I'm really not happy with how this blog has turned out.
Yes, there are some good ideas here, but what I've posted really doesn't make those ideas as accessible as I would like, and there are problems with the (lack of) organization and with not having had a clear idea of what I wanted to say at the outset.
Also, I can't go as deep into this subject as I would like without addressing the application, self defense, which becomes more important as one becomes more vulnerable with advancing age. I believe that it is possible to incorporate this consideration into one's physical activities without having it encroach into aspects of one's life where it does not belong, but this is something of a balancing act which I don't feel I can do justice to in this format.
So, I'm going to consider this a false start, which I may or may not ever get around to replacing. If not, it will have to stand as is, for however long Google consents to keep it online.
If I do come up with something better, I'll post a pointer to it here.
