72 here. Clearly some cognitive decline, but I still ride fairly strong. No accidents in years (touch wood) even tho my riding includes some steep descents. What I learned and adhere to is the mantra = 'speed may not be my friend'. My mileage is down some in recent years, probably around 2,000mi/year, but I also stopped driving to the MUP and ride much more on public roads from my doorstep; hence = the first descent of every ride is twisty with gravel edges.
On a road kinda like this - just tilted, with gravel driveways for most residents.
