“There is a tension between what is good for someone and what they want to do. This is because people, especially older people, like to do things as they've always done them. The problem is that when the brain develops ingrained habits, it doesn't need to think anymore. Things get done very quickly and efficiently on automatic pilot, often in a very advantageous way. This creates a tendency to stick to routines, and the only way of breaking these is to confront the brain with new information.”
