Subject: 61'st update on fly longevity experiments

    This is the 61'st update of my fly longevity experiments. Average
temperature was 22.0 C during this run. Here I test some more novel
supplements.
    The most interesting feature of this run is the poor performance of
the control#2 versus the control#1 bottle. This poor reproducibility
underscores the need for replication before any positive results with
supplements can be granted much weight. Using control#2 as a yardstick for
this run, implies a large number of positive results with supplements.
Using control#1 as a yardstick, only bergamot leaf and possibly periwinkle
yielded any interesting results. An average longevity of 67 days+ for the
bergamot population, that probably included some older flies to start,
exceeds the average longevity determined by virtually all published
experiments. However the reduced temperature, and the uncertain nature of
statistics (only 10 flies), does not preclude the possibility of a null
result in future replication studies (Run#72 - in progress).
