Subject: 167'th update on fly longevity experiments

     This is the 167'th update of my fly longevity experiments. Average
 temperature was 21.* C during this run. Estimated maximal longevity using
 the formula (363 - T*11.2) is 12* days.
     Although high doses of tyrosine dudded out before, I was encouraged
 to try much smaller doses. Thiamin acts against glycation, and zinc has
 some immune boosting effects in mammals.
     The control bottles did the best over all. 'nuf said.
