We've been married almost 35 years now. We met at the University of Utrecht, where we studied biology. After graduation we both taught the topic, but that was a long time ago. Nowadays the study mainly provides us with a lot of fun when we go for a walk. Among the hobbies we share are photography, art and travelling.

Anyway, we're in our fifties and have 3 children, two sons and a daughter.

Nelleke's hobbies are numerous. Among them are gardening, collecting movies & TV series (yes we've got everything ever issued on Star Trek, but are convinced The Sopranos is the better series), knitting, reading books, reading books & reading books.

She always carries a handheld and/or tablet with a suitable dose of books with her. And she's a member of Stitch 'n Bitch and contributes often to Ravelry
