No, I had no problems at all with it. However I think you may be right re quality of bones. I have had rib fractures. My own fault. I went on a ride at the show with my daughter. Didn't even think. Got slammed into the side of carriage as we were spinning around. I jokingly said to my husband that I probably fractured my ribs. This was before I realised the severity of my bone density. X-rays after lots of pain were clear. I had Physio for months. It wasn't until a bone scan picked up healing rib fractures that they were confirmed. Nine months later!! Apparently rib fractures don't show up early. They were at the site of my radiation which is not unusual. I have now become a grown up and no more show rides :(
