CNN.com hosted a live webcast today about the search for longer lives, and perhaps immortality. Aging experts like Dr. Aubrey De Grey and Dan Buettner discussed practical steps to living longer and cutting-edge research that could dramatically extend human lives. Some people in remote parts of the world can live to over 100 because of healthy diet practices and reducing stress. Eating less meat and lots of fruits and vegetables can lead to longer lives. Regenerative medicine, the emerging field of stem cell therapy and gene therapy, could dramatically extend human lives in the coming decades. CNN Chief Medical Correspondent Dr. Sanjay Gupta moderated the discussion. Dr. Gupta is also the author of the book "Chasing Life."
