What distinguishes people who live to 100 years of age?
According to the Gerontology Group, UCLA, in Los Angeles, almost all
centenarians are female and under five feet tall. This basic fact
correlates well with the fact that small dogs live much longer than large
dogs, namely 15 to 17 years, as opposed to 9 to 11 years, respectively.
Indeed the largest breed of dog, the Great Dame, often becomes gray at
age 3 or 4 and dies on average at about age 7. In 2011, Professor K. A.
Greer and colleagues did a regression analysis and found that the key
hormone, IGF-1 in 144 domestic dogs correlated in an exact 1:1 ratio
with the varying weight of dogs during aging. Thus, at least in domestic
dogs, high IGF-1 blood levels are critical in keeping death at bay during
aging. Therefore, it’s likely that the critical repair hormone IGF-1 is
essential to long life in dogs and quite possibly humans. In Okinawa,
100-year-old women have double the level of testosterone and other
hormones compared to 70-year-old American women.
Furthermore, I imagine that other key hormones and peptides from the
pinal gland could be important in preventing premature death such as
DHEA-Max, Pregnenolone-Max, SermMax and ReleasingMax.
I Now Turn To The Question: What Might be the role of IGF-1 in
people who live to over 100 years of age?
According to the Gerontology Research Group, UCLA, in Los Angeles,
almost everyone who lives to 100 years are female and under five feet
tall. This basic fact correlates well with the fact that small dogs live
much longer than large dogs, namely 15 to 17 years, as opposed to 9 to
11 years, respectively. Indeed, the largest breed of dog, the Great Dame,
often becomes gray at age 3 or 4 and dies on average at about age 7.
(See the graying great Dame in the photo.) In 2011, professor Greer and
colleagues did a regression analysis and found that the key hormone,
IGF-1 in 144 domestic dogs correlated in an exact 1:1 ratio with the varying
weight of dogs during aging. Thus, at least in domestic dogs, high IGF-1
blood levels are critical in keeping death at bay during aging. Therefore,
it’s likely that the critical repair hormone IGF-1 is essential to long life in
dogs and quite possibly humans (SermMax and ReleasingMax).
