Subject: 18'th update on fly longevity experiments
This is the eighteenth update of my fly experiments. The onion 4X
bottle is turning out unexpectedly to be a big winner, with a day 45
survival of 50%. By comparison by day 26, survivals in 5 out of 6 control
bottles were lower than this. Although high dose onion powder looks very
promising, I will need to replicate these good results before believing
them.
Cinnamon with a day 45 survival of 35% also looks promising. I will be
testing chitosan in the next run in combination with various fat
containing supplements, including onion and cinnamon. We'll see then if
chitosan's fat absorbing ability improves survivals yet further.
Adding yeast to the control bottles looks to be reducing survival.
Under sterile laboratory conditions adding yeast can increase survival
slightly. Since my own somewhat unsanitary experiments find yeast to be
deleterious, I take this to be an indication that pathogens are a
longevity limiting factor with my experiments. Nontoxic doses of onion,
sage and cinnamon may be offering life span extension primarily by
inhibiting pathogen growth. This renders my results questionable to say
the least and before any supplement can be conclusively stated to be
beneficial to fly longevity, experiments conducted under truly sterile
conditions would be needed. I will attempt to improve my own quality
control procedures in the next run.
Those with sharp eyes may notice that one of the paprika doped flies
sprang back to life on day 41, after being declared a goner on day 36.
