We live in a crazily youth-orientated world nowadays. It's a trickle-down thing. We see pictures of lithe, attractive celebrity couples such as Brad and Angelina or the Beckhams cavorting around, covered in tattoos, stomachs as flat as the singing in early 'X Factor' rounds.

I remembered being young in the late '70s and early '80s and growing up at the height of the Cold War. I remembered how scared I was of nuclear weapons, how often I though about them and about the possibility of everything and everyone I knew vanishing in a second in temperatures hotter than the centre of the sun.

There were some summers when every boy in Ayrshire seemed to be playing golf, and my dad taught me. But he was a terrible teacher - of everything. Learning to drive with him almost killed me. He was the world's most impatient man - awful short fuse.

I love England. I live and work here. My children have grown up here. I see no conflict between this and praying that my countrymen in Scotland never have to live another day under Conservative rule from London.

Real to Reel is a rare opportunity for new filmmakers to screen their work for industry insiders.

I've had a good career, some good experiences.

I used to work for a catering company - I waitressed for Harry Winston events. I remember being so hungry, I would eat when I was supposed to be catering to other people.

I started off with a company, InfoSpace, with my own funding. The company was listed among the most successful companies and I went on to start Intelius and Moon Express. Now, I focus my time on using the skills of an entrepreneur to solve many of the grand challenges facing us in the areas of education, healthcare, clean water and energy.
