I get that, though I'm just in ny 30s. I dont think its that I'm worse at games. I can still get good, but I dont have time to dedicate to it anymore.
If I sit down and play a shooter every day for 3 weeks, my twitch reflexes will start to come back.but I dont have that time. And if I do, I can't keep it up before work and life take ahold again.
The last game I played was CK3 with my cancer ridden and dying character. Seeing that he still refuses to die and my strong warrior son hasn't taken over yet, I feel pretty confident in my odds.
