Mad Men's runaway star, January Jones, has spoken up about her unsaid battle with misophonia, a neurological disability that manifests itself in severe physiological reactions to specific, common sounds. Taking to Instagram, the 47-year-old actress detailed her struggles with the condition:“For today, I'd like to talk about something that I've been struggling with my whole life, which is called misophonia. And it's gotten progressively worse over the years.”Jones also seemingly 'called out' her brother-in-law for his apparent flippant response to her strife:“I have a brother-in-law whose favorite food is chips. Just all the time, he eats chips.”The Emmy-nominated star added:“I have talked to him about this many times and he seems to think it's funny to eat chips around me now, because it's an ongoing joke to see what happens and see what I do. I just think it's really unkind to my issue and also very dangerous for him.”She concluded:“Otherwise, he's a really nice guy. And it's his birthday today, so happy birthday. I hope you’re eating a f*ck load of chips.”The video she uploaded to her Instagram: View this post on Instagram Instagram PostJanuary is the oldest of her siblings and has two sisters, Jina and Jacey, who are both working in Hollywood.About January Jones and her SistersJanuary Jones has two sisters, Jina and Jacey.
