I don't think immortality is necessarily the key to understanding the world. You have to be careful with what you think you're achieving. I'm all for science discovering amazing and fantastic things about our world but I think the motivations behind it are slightly askew.

When you write biographies whether it's about Ben Franklin or Einstein you discover something amazing: They are human.

For every five well-adjusted and smoothly functioning Americans there are two who never had the chance to discover themselves. It may well be because they have never been alone with themselves.

Young people discovering their sexuality must know they walk with a strong tradition and that they are not alone. They have a right to information without being pressured.
