Subject: 197'th update on fly longevity experiments

     This is the 197'th update of my fly longevity experiments. Average
 temperature was 27.6 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 54 days.
     This run retests some supplements which generated very modest hits in
 the past. In run #1 forskolin at a 10 mg dosage offered the best over-all
 survival. There was no control group in that run. In run #8 flies fed
 Kyolic Formula 100 aged garlic extract at a 75 mg dosage outlived the
 controls by a few days. Were these chance findings, or are they genuine
 life extension supplements?
     Forskolin at a 10 mg dosage failed to best the controls in this run,
 although a lower 2.5 mg did by a few days. Forskolin verdict: It was
 probably a chance finding.
     Aged garlic at a 75 mg dosage again beat the controls by a small
 margin. Verdict: Results are consistent with a modest anti-aging effect.
 However further testing will be needed before I would be completely
 convinced. Run #214 is again retesting aged garlic extract. It is
 interesting that only aged garlic extract appears to be beneficial.
