Will 49-yo Mark now have the life expectancy of a 19-yo Mark?

After two years of TA-65 use, his median length is now 12,500 (from an estimated 9,400) with a very nice drop in critically-short telomeres to 4.5% (from a baseline of up to 20%). So if you believe what most research is showing regarding the connection between shorter telomeres and longevity, Mark has gained over 30 years of longevity in a time where he should have lost three years.

Harvard/Northwestern VA study claims to predict cancer risk with telomere lengths

Men who developed cancers were compared with those that didn’t for the 13 years prior to diagnosis or exclusion by using a quantitative PCR measurement (which is problematic). Firstly, they found was two different curves with the cancer group showing a more rapid shortening trend. This is consistent with my stem cell theory of aging and most of the extant studies.

Same data, two opposite conclusions? – unless…

When data from the Copehnhagen City Heart Study was published in 2013, they concluded that shorter telomeres in leukocytes was not associated with increased cancer after adjusting for age but that it WAS associated with reduced survival from cancer http://jnci.oxfordjournals.org/content/105/7/459.long

In 2015, the same data looked at certain gene tendencies that promote telomere shortening and concluded that cancer survival was IMPROVED when shortening was enhanced in the telomeres.

Contradiction? Not so fast.

Telomerase in action (HD video)

Just a brief video showing an illustration of how telomerase works. I don’t believe there is an “End replication problem” as such because you want the non-stem cell ends to erode in the less valuable, differentiated and mortal cells. They are like drone bees that last months, unlike the queen bee stem cells which last years
