Subject: 179'th update on fly longevity experiments

     This is the 179'th update of my fly longevity experiments. Average
 temperature was 22.5 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 112 days.
     This run tested phosphatidylserine, relora, and vinpocetine. All of
 these supplements are supposed to exert neuroprotective effects. Of these
 three only vinpocetine increased late life survival. Run #192 is
 investigating vinpocetine again.
