The things I learn while editing. The book was about living healthily. This particular part was about diet modification and limiting the ingestion of animal parts and SECRETIONS.
WTF -- secretions? Ewwwwww. So, I fact-checked - 'cause that's what I do . . . it's a part of the job, and I enjoy learning new things—even when they're disgusting.
I'll never look at the phrase 'natural flavoring' the same ever again.
