Please allow me, dear reader, with honesty and caution to end with the following remarks.
In most of the links above , I refer to quite distant and disjoint parts of my life.
I am including many years, if not decades, during which the concentration was on only one of the above mentioned activities. Everything else would have been beyond my abilities.

All these activities have been pursued not only from intrinsic motivation, but also because of the strict limitations enforced by the age and health, both on my pianist friend Thomas Turner, and myself having severe vision problems.
I have to destroy the illusion of a magic abilities to easily move from one topic to another.
Currently, even the consolidation and gathering of all efforts makes more pain than I would have expected.
