Was: Calories/Height/Wt. Now: Lifespan extension

[Guest guest]

Hi :

I am learning to take your posts seriously!!! Many thanks for that

link to the CR Society page. You linked artid=10. But I have just

been reading artid=7. Fascinating. I wonder if it is true. It

shows two diagrams 'Lifespan of B10 and B6 mice'.

Those diagrams appear to indicate (unless they are mislabelled, or I

need a new pair of reading glasses) that when the 'B10' mice were put

on 44% CR at human equivalent age 30, the longest lived of them

extended their lifespan by ten (human equivalent) years.

*** BUT *** when the 'B6' mice were put on 27% CR (less CR) at age

40 (later in life) they extended their lifespan by 21 years (double

that of the previous example!!!)

I am personally hoping that these data can be extrapolated to age

60! If so then if started at age 60, zero% CR should extend lifespan

(by simple extrapolation) by about 40 years.

I suppose that either the diagrams are mislabelled or I am having

difficulty understanding them. Is it possible to clarify which it

is? In both cases the controls lived to age '98', so it doesn't look

as if 'B10' and 'B6' are different types of mice.

The mice populations (B10 and B6) do have quite different lifespans in terms

of months, though, so I think they are different strains.
