Avoiding danger is not possible. Yesterday at lunch I reached for a banana on my kitchen counter and felt such sharp pain in my shoulder that if I had grasped the banana I would have dropped it. The kind of pain where you can't breathe. Since then I have tried to be very careful what I do with my left--dominant--arm. I have found no way to predict what particular movement will cause pain when.
If reaching for a banana can cause injury, there is no safety anywhere: something I already knew.
