Callista Womick is an art model. And yeah, she’s naked at work. But she gets to work in collaboration with artists as they create their work. She talks about the strain posing can put on her body, what goes through her head while posing and answers the age old question: whose more uncomfortable- the artist or the nude model?

Check out Callista on Twitter @alackaschmatz. (And if you want to see some of the work produced during Callista’s posing sessions, check out whythepodcast.com)
