I am currently involved in part time cancer research, and we had this video presented to us earlier this week. The presenter is Dr. David Servan-Schreiber M.D. Ph.D., who talks about the overlooked lifestyle contributors and preventors of cancer. Very informative and I strongly urge you folks to take a look at his work and story.
