Aleks Krotoski takes a look at the way we use crutches, in both our offline and online lives. We all use crutches - from dummies to cigarettes, from computer games and snapchat filters to people or food. It’s distraction from whatever it is lying beneath the surface. But sometimes crutches stop being a short-term solution, and start being part of the problem. From here, life can get complex. How much do crutches help us, and how much does it hide the problems we need to tackle head-on? Producer: Caitlin Smith
