Subject: 130'th update on fly longevity experiments
This is the 130'th update of my fly longevity experiments. Average
temperature was 20.2 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 137 days.
Lipoic acid by itself was something of a disappointment previously.
This time a rather more expensive R(+) isomer was tested. One is reminded
ofthe saying "throwing good money after bad".
Aspirin had provided contradictory results in published experiments.
This difference had been attributed to the confounding effect of pathogens
in an experiment where positive effects were detected. Since I regard
pathogens as being a major factor in fly mortality in my own "homebrew"
experiments, there seemed to be a possibility of aspirin might be helpful.
The present results indicate that this may indeed be so, provided the
dosage is low enough to avoid toxicity.
