If your over 60,Fell off a ladder a few weeks back,landed in my wifes Mini Cooper ( close to grand worth of damage to the car).
Fractured My coccyx,my right elbow and my lower spine,I cannot even walk,living on some nasty drugs these days
Talked to a doc friend of mine,He said it is a proven fact that as we age we get subtle changes in the arterys that feed the brainbox.
Vertibral arterys the most,(noting can really be done about it)
Thats what happend to me,I looked up and passed out.
No more ladders for me,when I get better well train the wife to do that stuff
