    This is the 68'th update of my fly longevity experiments. Average
temperature was 23.6 C during this run. Choline and vitamin B12 share a
synergistic action in stimulating brain acetylcholine, so here I team
CDP-choline and methycobalamin to see what happens. Synephrine has been
recommended as a relatively non-toxic alternative to ephedrine for weight
loss. I've tested both before in separate runs, but here I pit both head
to head in the same run.
    Methylcobalamin turned out to be a dud, but CDP-choline by itself
provided the best longevity results overall. Initially both doses of
ephedrine, and the high dose of synephrine performed worse than control,
but late in the run ephedrine, and low dose synephrine beat the control
survival.
    Eventually I'll have something more to report on CDP-choline, but for
the next run I take another look at cinnamon and paprika.
