See above. In addition: we are both physicists by training. I have retired retired recently from a career in research at Philips (the Dutch electronics company); my wife is still full-time employed at the physics department of the Technical University of Eindhoven, as a member of the teaching staff.
We have a broad (classical) cultural interest (classical music, opera, the visual arts (both old and contemporary), design (!), literature and philosophy). Finally: we are walkers, not as active any more as we used to be, but still walking in the Lake District nearly every year.
