Mary Portas is not afraid of change and is never short of new ideas. An innovative bussiness woman, she transformed Harvey Nichols into a global fashion brand in the 90's and has graced our screens and our bookshelves in the two decades since. She's advised governments and developed clothing lines of her own. But now, at 61, how does she feel about the Mary underneath all of this? Is she afraid of slowing down? Or does parenting Horatio, who's just 9 years old, keep her feeling energised? Mary reflects on the importance of following your heart, and fixing her broken sleep pattern. We also hear from Nick Littlehales, who tells us how to create the ideal conditions for mental recovery and preparing for sleep.
