Doesn't sound like a complaint against "smart" rings; more like a general complaint against rings.

Also sounds like the author has done a great deal of work to improve himself, physically, and I can respect (and hat tip) to it, but he would definitely see the same issue with a wedding ring (except that you can usually resize those).

I wear my wedding ring constantly; even in the shower. I'm old-fashioned, and haven't really changed that much, since I got married (besides getting grayer and wrinklier).
