Subject: 192'nd update on fly longevity experiments

     This is the 192'nd update of my fly longevity experiments. Average
 temperature was 25.9 C during this run. Estimated maximal longevity (EML)
 using the formula (363 - T*11.2) is 73 days.
     In run #177 urea at 1/16 & 1/8 tsp dosages outperformed both control
 bottles, while in run #179 vinpocetine at 60 mg did well.
     The current results indicate that the previous results were either
 chance findings, or the results of possible antipathogen effects.
 Pathogens may not have been an issue in the current run, since EML was
 reached by control flies. In the past I have found that controls are very
 hard to beat whenever they closely match EML. Conversely whenever a very
 great advantage over controls is found for a supplement, this advantage
 usually largely vanishes when EML is used as an alternative comparison.
 True anti-aging effects are a very rare finding.
