Falling is a hazard that a lot of people underestimate the danger.
Unfortunately, My Mom and my Uncle both died due to a fall when they were in their late 80's.
I suspect when you fall, you cannot put your hands up in time to break the fall when you are very old....and ultimately your head hit the ground or a hard object. Both my Mom and my Uncle also refused to use a cane which would have helped their balancing.
I do recommend people use a cane when they get in their late 70's before it is too late. You should not be stubborn or embarressed about it. A Serious fall is like a heart attack. If you survive a heart attack, you make some changes to avoid a second one. If you survive your first serious fall, you start using a cane. Unfortunately, my Mom and my Uncle did not survive their first serious fall.
In addition, my Mom fell during the night going to the bathroom. I also recommend this product below that allows you to see at night. It is a great motion sensing product to have to avoid stumbling in the dark to go to the bathroom.
