I too have had some very bad falls in the last year. There was the famous one where standing in front of my greenhouse, I just lost all balance and tumbled into it, suffering huge cuts to my shoulder, needing hospital.
I also find I have no control once I fall. Birte's description of "a shot deer" is exactly right. However, I have not fallen for months by taking things more gently. I also wonder whether to have my ears syringed, wax build up can affect your balance.
Must go, Yoga today for one and a half hours.
