If you so happen to watch "CBS This Morning," then you might know that co-host Charlie Rose had heart surgery earlier this year. But what you may not know is that Rose's replacement valves are courtesy of a pig and a cow.
Rose recently talked about his artificial heart valves with "Late Show" host Stephen Colbert.
According to CBSNews.com, Rose said the doctors "went in there and gave me a new valve -- a cow valve." He added that his other valve is a pig valve and joked, "I've got a pig and a cow competing to send blood to my heart."
