Subject: 53'rd update on fly longevity experiments

    This is the 53'nd update of my fly longevity experiments. All bottles
contain 1/4 tsp citric acid as a standard additive. Recorded average
temperature during the experiment was 25.9 C. Slightly more water was
added to the gelatin bottle so as to prevent the flies from drying out.
   In this experiment I seek to replicate the results with soy protein,
and rice polishings, which had the two best survivals in run #51. The
current results confirm that these supplements are beneficial for
survival. Gelatin may be detrimental because it is a low quality protein,
that may impare immunity.
    In the next run I take a closer look at rice, and soy proteins.
