“But forgetting isn’t just a loss that comes with age. It’s a normal part of the memory process. We don’t need to remember a lot of what happens to us – what we made for dinner two years ago, where we left the car the last five times we parked in this lot. Those are examples of things that aren’t useful to remember anymore.

Research suggests, and my work with memory-related conditions corroborates, that some people have an inability to forget traumatic events. This characteristic is partially responsible for conditions including depression and PTSD.”
