A man in Canada says his lung “flopped” because he sang so hard at a Carrie concert. It’s not clear if he meant to say collapsed, but he did post a photo of himself in a hospital bed wearing an oxygen mask. Carrie saw it and posted a response, saying, “What the what? I hope you’re alright. It was great to get to see you. Thanks for risking your life to be there.” https://twitter.com/carrieunderwood/status/738048505491509248
