Well, that’s probably a long, complicated question, but as I am in imaging and as CT scanners developed and as we had questions, well, how do you, what do you do for this finding? It became clear to me, and to others, that it’s all a group of us working, that it could, it would be useful for CT screening, and then as we started to do our project, I saw that we could find these small, early lung cancers and that we could save lives, and that is a very powerful incentive.
