75 now. Ride three times a week, either my road bike or my gravel bike. Typical rides 15-35 miles, I love hills, live in Oakland where I go out my door and have great uphill rides for miles. Just did a great mountain trail downhill last week on my gravel bike, it was GREAT. I was scared to death on one stretch, the fast steep, rocky downhill only two feet wide with a 20 foot drop to a rocky creek bed. I just retired after decades of riding motorcycles on the track, and that downhill was scarier.
