X-Message-Number: 31892 From: Date: Fri, 21 Aug 2009 09:47:53 EDT Subject: Re: CryoNet #31888 - #31891 Hi Alan, Leaving out the growth hormone/brain cancer connection and Linus Pauling's death at 93, there are only four who died "early" from cancer. Missing from the analysis is the size of the cohort to which they belong, as well as its median age. The cohort is composed of all the people public or private who would have come to my attention as people with life extending life styles who died within the past decade. If this cohort numbers 300 with an average age of 60, about thirty deaths could be expected, with maybe eight cancer deaths. So the hazzard ratio for cancer deaths would be .50 And only eight deaths would have been noticed where thirty would be expected. Since the size of the cohort is unknown no such analysis can be undertaken. The fact that the relative ratio of deaths due to cancer vs vascular disease is independent of the cohort size does allow an investigation into this issue. It should be close to one, but no vascular disease or death has come to my attention. This situation allows an hypothesis that the relative protection from vascular disease is much greater than from cancer. And I for one am beginning to focus my efforts more on prevention of cancer.
