My current and past hobbies and interests include the following:
I am an avid runner, and have, e.g., completed 11 marathons, 22 half-marathons, and a 30K race since 2005. See my race results on
I like playing rounds of golf, but will only record an occasional par. I sometimes cycle or hike on trails with my family. In my youth I actively played tennis and tabletennis.
I enjoy photography, recording the life, activities, and trips of my family. We like to do escape rooms as part of our adventures.
I collect stuff, such as coins, stamps, and smurf figurines.
Throughout my life I have been a big sports fan. I watch soccer, cycling, speed skating, golf, tennis, biathlon, and racing to name a few.
I have been a lifelong fan of progressive rock music, and have attended more than a hundred live concerts. If you are interested, try out one of these websites: progstreaming, progarchives, or Dutch Progressive Rock Pages.
I enjoy reading, although I don't find much time. My favorite author was the late Oliver Sacks. For nostalgia's sake, I also read comic books such as Suske & Wiske.
I like watching TV shows and movies across a wide range of genres.
I support the Breast Cancer Research Foundation, the Juvenile Diabetes Research Foundation (JDRF), and the Children with Diabetes organization. I encourage others to do the same.
While I was a student, I chaired the Leidsche Flesch student union in 1986.
I used to play chess in my youth. With the St. Adelbert high school
team we captured the Dutch National Championship in 1983.
