Keep at it, you never know. I am 77, and I play for enjoyment, and i will never hold my own at blitz or bullet, which I like only for the buzz. I enjoy the odd win, and never get heartbroken about the losses.
As for the longer versions, I study lots of tactics, and believe that playing only when reasonably fresh, and really concentrating will at least stem deterioration, and I have managed to slow my decline, but your relative youth may leave room for a little improvement.
Dropping pieces and allowing simple combinations comes easily if you play tired, or without concentration, and if that happens, then we all know that resign time is close unless the opponent allows you back in the game, which players at our level do not usually allow.
universityofpawns: I'm 65 and I'm still interested in improving at chess and other things.
I'm close to finishing the online MIT 18.01 calculus course, which I undertook partly as a test of my mental capacity. My memory is not as sharp as it once was, nor do I have quite the stamina and concentration I possessed as a teenager. But I do have more patience and perseverance now, which is no small compensation.
I now know calculus better than I did after two semesters of calculus as a college freshman.
My sense is the peak one can achieve drops as you age, but there is still room to move if you are not near that peak.
