New updating period for this blog

Visitors of this blog should know that my wife’s brain stroke, followed by a long recovery period, absorbed a lot of my possibilities to update this blog.  As she is back home now, but still needing my support for additional kinetherapy and ergotherapy, I see some more chances to update the blog.

I count on your understanding and thank you for your patience.
