With time, many of the facts I learned were forgotten but I never lost the excitement of discovery.

Yet the effort to inform the public also encouraged responsible public discussion that succeeded in developing a consensus for the measured approach that many scientists supported.

Today, it is research with human embryonic stem cells and attempts to prepare cloned stem cells for research and medical therapies that are being disavowed as being ethically unacceptable.

Paradoxically, no such embargo exists for the drugs and therapies that have revolutionized the treatment of serious diseases although many of them were created with the same technologies.

Your job, what you do every day, I think it takes a high priority over anything. That was something I dedicated myself to throughout my career.

For me, I spent months on job boards in 2010 and was frustrated by the experience. It's antiquated and clunky, and there was nothing about a particular job posting that helped me favor one company over another. You literally get a list of 5,000 jobs that look the same.

It's thought of as an eccentric thing for an actor to really try to maintain quality control through the whole career. Most people think, 'You just work. You just keep working.' And in some ways I wish I could be a guy who's just a workhorse.
