Subject: 97'th update on fly longevity experiments

    This is the 97'th update of my fly longevity experiments. Average
temperature was 21.1 C during this run. Estimated maximal longevity using
the formula (363 - T*11.2) is 124 days.
    Blueberries have exerted some significant neurotropic effects in
rodents. So it was with some surprise, that I found blueberry juice to be
ineffective in previous fly longevity experiments. I theorize that
blueberry (and prune) juices may have previously been exerting toxic side
effects due to too high a dosage, since the juice fed flies were incapable
of flight. I try small doses of these juices here, to test this idea out.
    Neither blueberry nor prune juices prevented flight in the flies in
this experiment. However no longevity benefits were noted either.
