1. She Uses Spoon Theory

To manage her MS, Blair uses spoon theory to get through each day. She explained to The Guardian, “You learn to think to yourself, ‘OK I’ve really only got two spoons today, so don’t shower, and I can’t eat yet because I don’t have time to vomit. And the lights and the stimulus on set, all the things I normally love, can leave me quite befuddled. My mind will trip up.”

2. She Wasn’t In A Hurry To Lose The Baby Weight

After having her son, Blair wasn’t in a rush to lose weight. She told Us Weekly, "I actually haven't lost any weight since the day I left the hospital. I still weigh the exact same number. I haven't really been focusing on that at all, because I've been running around to different things like Toronto [International Film Festival] and Venice [Film Festival]."
