Everyone is different. For some, there does come a time in life when interest change, and desires alter.
There could very well be a limit where I say, "I'm done". I'm not there yet, but I am at the point where there are only a handful of guns that I was ever interested in that I have not either owned or had a chance to thoroughly check out.
My personal situation changed this past year, and my income essentially halved. so, I don't have the disposable to buy like I used to, but then, I don't need to. In fact, I may even get a chance to shoot some of the dozen plus I've had for years and never got to shoot for one reason or another.
In fact, I've even thinned the herd a bit this past year. There are still a few pieces on my want list, but they are rare.
Also, I'm not really interested in anything new....that cut a lot out, right there,
