My brother Keith and I ventured into China for a day. We stopped in a little Chinese clinic to check our health. A doctor came out to examine us. He held us each by the wrist and concentrated. End of examination. Keith was pronounced fit, but I was "nervous". The clinic offered a variety of cures for what ails you -- including nervousness. I remember deer horn, bear gallbladder, and royal jelly. Didn't try any of that. Keith and I did dip into the complementary crispy black ants though. We each had several spoonfuls. Crunchy and tasty. I'd like to have a local supplier.
