From unblinkered

1. I must admit to being slightly confused by your family status: as far as I can tell, you are an Englishman cohabiting with lemur_catta and a plethora of cats in Canada, have a daughter living elsewhere and a son (I think)? Please clarify!
I realise this is a very personal question, and you don't have to answer it if you don't feel comfortable doing so.

That's about right. I was married to an Australian but we ended up getting divorced. I have a son and a daughter from that marriage who live with their mother in Canberra. The lemur, the cats and myself all live in a downtown Toronto condo.

2. I didn't know you had an interest in book arts! How did you get into that?

Walter Strachan taught at my school though he was pretty much retired by the time I was there. Still, it was Walter and his amazing collection. knowledge and enthusiasm that got me started.

3. Where should I travel if I want to experience the ultimate culinary experience?

Can there possibly be a single answer to that? Paris probably has more good food per m^2 than just about anywhere else (at a price!). Thailand was amazing (and cheap). People say great things about Hong Kong but I've never been.

4. I don't "get" physics or chemistry, but was fairly good at maths in school and enjoy doing the calculations that crop up at work. In your opinion, is this a major gap in my education and should I attempt to rectify it? If so, how?

I think it is worth trying to get a grip on modern physics and cosmology. It's just so weird that it's fun. Lisa Randall's Warped Passages is highly speculative but it's up-to-date, very accessible and she does know her stuff.

5. I always love checking out your "current music". What is the furthest (distance/money/general hassle) you have ever gone for a concert?

I'm not sure. I know that the most momentous concert decision I ever made was to go see Dick Gaughan at a pub in London c. 1979. I had to be in lowestoft first thing next day and would normally have taken the train and stayed obvernight. Instead I decided to drive up early in the morning. Unfortunately that trip ended with me in Ipswich General getting two dozen stitches in my face.
