We always had lutefisk for Christmas dinner, after...

Dad was a chemistry professor at Saint Olaf College in Minnesota, then Oxford College in Minnesota, and a very active member of the American Chemical Society education committee, where he sat on the committee with Linus Pauling, who had authored a very phenomenally important textbook of chemistry.

The long, cold Minnesota winters instilled in me a fascination for exotic far off places I aspired toward a career in tropical diseases and world health problems.

Now a cholera epidemic was sweeping through Southeast Asia and south Asia in the early 1970s, so I started medical school and I joined a laboratory to work on this.

My dad encouraged us to fail. Growing up, he would ask us what we failed at that week. If we didn't have something, he would be disappointed. It changed my mindset at an early age that failure is not the outcome, failure is not trying. Don't be afraid to fail.

I was a mixture of being incredibly old for my age and incredibly backwards. I was born quite old, but then I stopped growing. I lived with my mum and dad till I was 30.

You get to a certain age and you can't judge yourself on your dad or your parents.

If you love somebody, you love them. My parents had a 25-year age gap between them and my mum was the breadwinner, my dad the house husband. I'm a strong believer that a good relationship can work, whatever the situation.

With the song 'This Christmas' I wanted to do something that was kind of different. I mean, Donny Hathaway is an amazing artist. So I wanted to bring my flavor to the song so when people over the age of 45 or 50 hear it they'll be like 'OK, he did his thing with that record.' It's like I can appeal to everybody and not just a younger demographic.

My mother was a professional sick person she took a lot of pain pills. There are many people like that. It's just how they are used to getting attention. I always remember she's the daughter of alcoholics who'd leave her alone at Christmas time.

'The Christmas Song,' by Nat King Cole, is not only a masterful performance to me it just sounds like the holidays. I've never sung it, because Nat's version is so perfect. I gotta leave it alone.

Christmas lights may be the loneliest thing for me, especially if you mix them up with reindeers and sleighs. I feel alone. I feel isolated. I feel I do not belong.
