Subject: 188'th update on fly longevity experiments

     This is the 188'th update of my fly longevity experiments. Average
 temperature was 25.2 C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 81 days.
     In this run I check to see if reducing water content in bottles
 containing nattokinase can reverse its toxicity. Also in run #181 a 1/2
 tsp dosage of bacillus natto turned out to be helpful. In this run I test
 to see whether this was a chance finding.
     Even though the fly food was not wet this time, nattokinase still
 proved to be toxic. I speculate that this might be due to an induced
 protein deficiency, which might have been blocked by a protein
 supplement. Bacillus natto itself offered no benefit this run, so I
 presume the previous results were a chance finding.
