We can be preventative that prevention can be personalized and more importantly, it's going to become increasingly participatory.

Imagine if we could create the world's first rating system, in which we could score foods according to their antiangiogenic, cancer preventative properties.

There is going to be a big shift towards preventative medicine as we start to be able to identify all of the risk factors that we have as individuals.

And if we can get in at the bottom and understand the genetics, we'll have a window on the way the disease works, and a whole new way about thinking about disease therapies and preventative treatment and so on.

I hadn't really thought that it could be sort of preventative in nature, until I was about 20, when a number of things happened in my life in quite quick succession, really serious things which just flipped my life upside down and all of a sudden I was inundated with thoughts, inundated with difficult emotions that I didn't know how to cope with.
