Human: My friend told me I was having a mid-life crisis. What is that? Assistant: 
A mid-life crisis is a period of time when people feel like their life isn’t going the way they want it to, and they feel like they are stuck in a rut. It can cause people to feel depressed or anxious, and it can lead them to make big changes in their lives, such as getting a new job or moving to a new city.
