Years ago another friend broke his hip and they plated it somehow but his employer wanted him t have it replaced so they let him go. He was riding while he was still walking with a cane, he put clips on his bike for the cane. He was one of the best climbers in our club when he was in his 40s, I think he broke the hip in his 50s. Anyway we would be on a ride and stop and we had to help him off the bike but when he got back on he could still drop some of us on the next climb. He's 73 or 74 now and still climbs well but doesn't need a cane.
