The first thing I became interested in in terms of 'Brain Storm' was neuroscience, and that is like saying you're interested in the universe. So ultimately I knew if I was going to handle this in a fictional format, I would have to take a subsection of neuroscience, and that turned out to be the use of neuroscience in criminal courts.

I always wanted to be a writer... 'Critical Care' was my first published work. I was 34 when it came out. I was accumulating 'Critical Care' for years. I would go for a whole year and not touch it. And then I'd go back to it.

I'm always working. I don't really set limits. I tend to go in bursts. And in between, I'm doing my taxes, answering the phone, and all those kinds of things. I waste a lot of time. Computers take a lot of time. I love computers.
