58 with a similar background (except that I'm a man) and I have no intention to stop.
I'm essentially a PC gamer but had a few game consoles too (until Dreamcast), which I ditched as soon as PCs were able to provide a decent platform for modern gaming. I'm a modder and occasionally a tweaker so I prefer having total control over my gaming environment than being restricted by a closed system console.
I love many game genres, my favorites being immersive open worlds and strategic action and stealth games (à la Ghost Recon Wildlands or Mass Effect) but I don't limit myself to those. Each genre brings its own amusement and interest, either honing your reflexes or challenging your cooperation skills or your memory.
And above all, gaming is fun!
There is no age cut off for enjoying challenging both your mind and reflexes, nor to have fun. And imho enjoying gaming at our ages is one of the many symptoms of still being a young soul.
