It seems like there are some older guys playing more than last year. Evidently Raonic isn't ready to throw in the towel, and I saw that Nishikori is trying to make a comeback. Fognini still kicking. I suspect Stan will be the next big name to hang up the racket, after Murray (unless Rafa beats him to it).
So on to some research. Below is a list of the years in which players won their last title (even if it was their first and only). It is worth noting that of the 18 titles so far this year, the oldest to win one is Grigor Dimitrov (b. 1991).

Forgive me for any errors - I might have got one or several guys wrong and/or listed them more than once.
As is often the case, I got a bit carried away...I kept going back, because I wanted to see who was the first player born in the 80s to win their last title...that would be Andreas Vinciguerra, who won his only title right after turning 19 years old. Born the same year as Roger Federer, he won a title before Roger's first. Talk about two careers going in different directions!
Anyhow, if you read any of that, it might be going down memory lane...lots of names I haven't thought about in awhile, even among the more recent 5-10 years. It is also a way of getting a sense of guys who didn't quite turn out as expected, for whatever reason (e.g. Mario Ancic, Robin Soderling, etc).
It is crazy to think that Stan Wawrinka hasn't won a title since 2017 - that's seven years ago! He's been around, but hasn't been anything close to his former self since 2020, when he reached his last Slam QF and finished #18 (partially thanks to the wonky rankings that year).
Milos Raonic isn't on that list because he was born in the 90s, but he hasn't won a title since 2016.
Anyhow, good old Ivo Karlovic is the last 70s baby to win a title in 2016, the year he turned 37. Of the 60s baby, it is Francisco Clavet way back in 2001, the year he turned 33. I think this illustrates how players have been aging out a bit later - Roger's gen, but more so the Rafa-Novak gen.
One final note, you can see a bit of a "bulge" in 2016-17 as a lot of 80s babies won their last titles, and then more of a trickle since then. The corresponding "bulge" for 70s births is somewhere in the 2000-05 range, so correspondingly earlier.
It begs the question: who will be the last of the 80s babies, and in what year? It is probably easy money on Novak, and my guess would be 2025 or '26, depending upon how long he wants to hold on. Adrian Mannarino is a guy who is having a nice extended prime - he's never been quite a second tier guy, but had his best season last year in 2023, winning three ATP 250 titles and finishing #22.
