Subject: 121'st update on fly longevity experiments
This is the 121'st update of my fly longevity experiments. Average
temperature was 22.7 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 108 days.
Here an interesting supplement called theanine has its effect on
longevity tested for the first time. This run also continues testing
various cooked beans.
Theanine is believed to be the major immune stimulating agent in tea.
I was hoping for some modest increase in average lifespan. This
expectation appeared to be fulfilled in the present experiment. No
evidence for a dose/response was found, so it appears small doses are
maximally effective. Although there was some increase in maximal longevity
from the control's 61 days to 88 days, this was still much lower than the
estimated maximum longevity of 108 days.
Of the beans, some interesting results were found with the 8% white
kidney bean bottle. This result will have to replicated before a chance
finding can be ruled out. No benefit had earlier been found for red kidney
beans.
