Thanks to Keith S for the headsup about the old wive's tale.
I once had a classical guitar teacher, long ago, who advised me on that gelatin makes strong fingernails tip.
And now, after years of eatin' that crap maybe once a week I find that my fingernails are likely just strong claws to begin with.
Will probably continue to eat it because the sugar-free Jello mimics a dessert and doesn't add to the calorie count enough to bother, though.
Thanks again, Keith.
