I am not as clumsy as I was, but that is not saying much. Actually I learned a lot of balance from karate, but I still forget where my arms and legs are at times and knock things over or spill things.
Like I am great at rollerblading, but standing still with blades on I fall on my rear every time. Horrible, but funny for my family. And I have a bony rear so it is painful!
One time I was ice skating and I fell and the blade sliced my hand open. The people there were concerned because it was just a passing attraction and they didn't want to be sued.
I have also run in to people on both bike and horseback. You would think after the first time I would learn. I loped in to my sister because the confounded horse wouldn't turn. What was sad about that is the horse was owned by a seven year old girl and the little kids rode him easiily. The horses were ok. He turned at the last instant and only I flew in to my sister. My sis and the other horse were also fine, they were going at a walk.
I have had similar experiances of falling off on three of the four horses that the little kids ride. What is funny about this is that I never fall off "trouble horses" In fact, my teacher routinly puts me on horses that haven't been ridden in a while, or are testy because I can handle them. I only fall off those that a four year old can ride.
I don't bruise or bleed easilly, so I recover from most of my encounters with solitary objects quickly. However, I think in our family I have had the most stiches, but I have never broken a bone, on been put under for any kind of surgery.
