One thing I found boring when I was younger was old people talking about what it was like to be old. So if you're young, don't read this.
So what's it like to be forty? Some people say they don't feel any different to when they were 20. That's not true of me, hopefully I've learned something in the past 20 years. I don't feel much different to yesterday. On the other hand though, people who are old enough to retire don't look that old.
