Reader’s Digest asks: Would a good night’s sleep be worth scoffing down the entrails of sea slugs or replacing your toothpaste with Fido’s ear wax?

The Hair of the Dog might cure a hangover, but back in the day, ear wax of the Dog was the go-to cure for insomnia. According to Gerolamo Cardano (1501-1576), a doctor and mathematician in Renaissance Italy whose other credits included being a founder of probability theory, sweet dreams could be yours by rubbing some canine ear wax across your pearly whites. I’m not sure your teeth (or Fido) would agree.
