On Thursday, Kate Middleton and Prince William stepped out for a joint appearance in the name of mental health. The pair visited a London hospital, where they met with Johnny Benjamin, a suicide survivor, and Neil Laybourn, the man who saved him. Dressed in an emerald green coat and black pumps, Middleton and her husband, who wore khakis and a blue sport coat, spoke with Benjamin and Laybourn about the importance of tackling the stigma associated with suicide and mental illness.

I was just blown away by the statistics," William said, according to people.com. "For both of us, the mental health piece has got lots of aspects. It's such a big issue that we need to do something about it. We feel it's been raised higher up the ladder. It's suddenly bubbling just under the surface. Now we need to get up to the next level, to the surface." Kate added that through her work with addiction, homelessness, and knife crime, she's learned that many of these mental issues stem back to childhood.
