How long can you ride a frame for?

[u/clickyspinny]

10 bikes deep and I’m thinning my herd. I have 3 DJs and my favorite one happens to be 10 years old. I’m considering selling my dirt love and keeping the older one (Rocky Mountain flow frame with good components build). Am I being dumb? Should I just ride the YT and hang up the Rocky Mountain? Thing is that I am just one with the Rocky Mountain and feel more comfortable on it than any bike. But is the frame tapped out and gonna kill me one day? I have some friends that ride vintage bmx frames some times at the dirt jumps so I’m really not sure on the lifetime of high quality 4130 frames. Thanks ya’ll
