I'm sorry to hear this happened to you... hope your poor head is okay. I have the impression falls are a major cause of injuries in older adults. I live in an area where there are lots of us older folks. And I know there have been a number of incidents of falling recently just within the complex I live in alone. So far I haven't had any falls yet. But I know that anytime something such as this happens to a person it tends to make one apprehensive. So I'm not surprised you're feeling anxious & scared. Hopefully you will be able to avoid a repeat performance.
