Sore Bones

I had a small mishap on Monday when we were at Clachtoll Broch. There is a low stone lintel across the doorway of  the broch, where a wooden door probably once stood. Foolishly I banged my head on it, but that wasn’t the problem. I immediately recoiled backwards and sideways and hit one side of my back on one of the big stones in the passageway. Despite me wearing a t shirt and fleece, it was a sore blow, and to my dismay it continued to be sore, in fact it became even more painful over the next several days. I wonder if I have cracked a rib, or whether it’s just bruised. It’s slowly improving now but it concerns me that my bones seem to be increasingly fragile. I know that I have osteopenia which probably explains it. 
This evening we watched Mission Impossible: Dead Reckoning Part 1. It was full of action scenes. I couldn’t help noticing that when the main character, played by Tom Cruise, parachuted into a train right through a glass window, not only did he show no distress but he immediately started fighting the baddies. In fact shortly afterwards he climbed up onto the train roof to fight some more, ducking down nimbly when the train went through tunnels. Then the front part of the train fell off a bridge and Tom had to climb upwards through several train carriages that were hanging vertically over a vertiginous drop, supporting the weight of his female colleague with one arm as he pulled her to safety. Needless to say I couldn’t have done any of that. In the unlikely event that I ever parachute through a train window I would be covered in cuts and would probably break several bones. The baddies would have to help me up from the floor, dry my tears and make me a cup of tea!
