If you, like me, ever wondered what the origin of the word vet was, Wikipedia naturally has the answer:
“to vet was originally a horse-racing term, referring to the requirement that a horse be checked for health and soundness by a veterinarian before being allowed to race. Thus, it has taken the general meaning “to check”: “The attorney vetted the documents before using them to make his case.”"
I just heard that term in a meeting and I had to look it up. I wonder who first used that term in a context outside horse-racing. He must of got some wierd looks :)
