How old is Robin Smith on Channel 4 News?

I assume you are referring to Robin Smith of KMOV in St. Louis, a well-respected news reporter who has had a long career in journalism in the Midwest. I do not see her birth-date on line, but she seems to have come into journalism around the same time as Oprah Winfrey did (early 1970s), which would make her about 56 or 57 years old.
