Of mice anyway. Which makes you wonder about the wee little beasties running around on AA.
Anyway, according to
this study, jet lag kills mice.
-- The young mice were not affected
-- Just 47% of older mice whose clocks went forward each week survived
-- 68% of older mice whose clocks went back each week survived
-- 83% of older mice whose clocks did not change survived
-- Daily corticosterone levels were not affected in any of the older mice (corticosterone levels are linked to stress, which is said to cause ill health)
I think what annoys me most is that younger mice aren't affected. Really, youth is so wasted on the young.
