"Tiny portions of ethanol, the type of alcohol found in alcoholic beverages, can more than double the lifespan of a tiny worm known as C elegans." So larger amounts of alcohol probably double the lifespan of a larger specimen like a human, right? That's the way I'm choosing to interpret this finding.
No, it just means that a mutant strain of worms will eventually
take over, and consume all of our alcohol (and live forever).
Since when were you concerned about longevity?
