I definitely felt older back in my early thirties, but I feel like I got younger now in my mid 40s. I think it's because my kid is in college and doesn't need me as much as they used to. Plus, I'm debt free and make enough money to not worry about the cost of going out.

In my late 20s/early 30s I was under water on my house, not getting paid enough, and had a small child. It was clear that I had to step up and "be a man." Which, I intuitively think had a bigger effect on me than simply getting older.
