Julian's Case Study

Julian describes his daily routine:

“I am constantly terrified that our house will burn down because of an electrical fault. Every night, I have to go around and check every single plug socket and light switch in a specific sequence, five times over. If I lose count, I have to start the whole routine again. It takes me nearly an hour to get to bed.”
