I live in Capelle aan den IJssel in The Netherlands with my wife, Ewa Mendys-Kamphorst, and two sons.
On holidays, I enjoy walking in the mountains and visiting old places. I'm still amazed and happy by the beauty of Andalusia. Recently I also have rediscovered kayaking. That's a good thing. In the Netherlands beautiful rivers and creeks are somewhat easier to find than mountains.
Also I love playing games in my free time. Varying from board games, to miniature wargames and roleplaying games. Maybe that explains why I followed game theory so long ago...
