Aside from a pact with the Horned One, the secret to good health, long life, and eternal youth is to eat lots and lots of fresh vegetables: hence my decades-long Evil Plot to Get the Pagan Community Eating More Fresh Vegetables.
Not that it's been hard, you understand. Everybody likes good vegetables. In modern paganism's Potluck Culture, the bowl is always empty by the time I bring it home.
I first discovered Purple Pickle years ago while living in the Middle East. Every pickle-seller down at the souk would always have huge, eye-grabbing jars of pickled cabbage and cauliflower that glowed a radioactive neon-purple color.
Gods, I'd think. I don't know what they put in there to make it that color, but I don't think that it's something I want to eat.
More the fool, me. The dye, of course, is all perfectly natural.
Oh, and as for that pact with the Horned: let me recommend it.
Vegetables aside, it sure has worked for me.
