There's this interesting thing called the U-Shape of Happiness. Happiness is quite high in kids and teenagers, and then it goes down, down, down, and reaches rock bottom in your midlife, but then it starts going up again and actually remains quite high until the last couple of years of life. Why are people less happy in midlife? One reason is it is the least amount of change. If you think about it, when you're a kid, things are changing all the time. I mean, you're changing, you're growing, right? Then you're in the 20s. You're trying different things. You're trying different partners. You're trying different professions. Then comes midlife, and things are similar. Most people stay in the same place because maybe people have kids. You're maintaining. Now, counterintuitively, at an older age, once the kids get out of the house and maybe you're retired, in fact, you're starting to change again. It's a totally different life now.

You literally just explain the midlife crisis and the journey of happiness of the human beings through the lens of neuroscience. That's so cool.
