I was taken out of school by my dad when I was 11 and lived in Mexico City, then later in Paris. I went with him to excavate in Bolivia and Peru. I never finished high school. I was a straight F student anyway. My father admitted to me later that he'd thought I would come to no good.

My mum and dad ran a family cafe in Sligo for 35 years and worked long hours. We grew up in a very hard-working family and had a lovely atmosphere, as we lived above the restaurant. It definitely made me want to work hard, whatever I chose to do. As the baby of seven kids, I was definitely a bit spoilt.

In 1967, the world health community launched a global effort to eradicate smallpox. It took a coordinated, worldwide effort, required the commitment of every government, and cost $130 million dollars. By 1977, smallpox had disappeared.

Working with franchises can be challenging, but at the same time I really did enjoy working on 'Star Wars,' for example, and I have done a lot of 'Dungeons & Dragons' games, but I still enjoy it very much.
