Robbie Robertson & Dr. Shamir Mehta

It was a brotherhood until it wasn't. Once Were brothers, the documentary that opened this year's TIFF, chronicles the story of one of the most iconic rock bands ever, The Band. It tells the story from Robbie Robertson's perspective and Libbie Znaimer sat down with the 76-year-old star earlier this week. AND It has been a conundrum for doctors treating patients after a heart attack caused by blocked arteries. Should they try to prevent a second heart attack putting stents in arteries that are only partially blocked or is that too invasive? A study out of McMaster University has answered that question decisively. Dr. Shamir Mehta is the lead author.
