Interesting enough, though far less interesting than it was when I was in my 20s/30s. I've found as I have got older that what I consider "interesting" has changed.
Until my DD was born I had a very short attention span and craved "interesting" situations to a point where it bordered on self-destruction.
I was interested in what I then called passion/romance but I would now call feckless men who can't make up their mind and won't commit.
I thought I was interested in passionate debate and discussion but a lot of that was actually drunken evenings being ranted at by people with strong opinions which they feel the world needs to know.
I thought I was interested in being as ambitious as I possibly could be and having a "prestigious" job which I could sound impressive talking about. Until I discovered that a lot of "prestigious" jobs are actually horrendously exploitative.
I thought I was interested in drinking too much and occasionally dabbling with drugs and they underpinned my social life.
I still get bored quite easily and I still need to be stimulated but I increasingly value stability, honesty, calm and routine. And I now value being around people who I can rely on and who aren't bullshitters more than people who are "interesting" for its own sake.
It's a trade off between "interesting" and "comfortable" to some extent: I wouldn't want to sink so far into middle aged comfort that every day was exactly the same and I had nothing more to look forward to than watching TV with the same person every evening. I do think having some mental stimulation and change in your life is absolutely critical to staying alive.
But I no longer crave difficulty and challenge for the sake of it and I feel much happier for it.
