As I have gotten older, my tolerance for risk has changed. I now ride well below the edge of my abilities "most of the time". I have to admit to getting carried away now and then, feeling like a kid. Those moments are worth the price of admission. If I feel a little spooked, I back it down a lot and have learned to listen to that voice, there's usually a reason for it. I hope to never call it quits, but if the time comes that I feel like I'm a risk to others or if it's not the same good feeling it's been for the past 48 years, I'll hang up the helmets.
