Grannyknot & others, I so agree with you. There is a certain age when you stop falling over and start having falls as if you were some passive object like a Joey that rolls over at the slightest push.
An 80 year old friend courteously stepped back on a pavement to let a mother and push chair get by, didn't realise how high the kerb was, misplaced his foot, fell over and broke his ankle. He got really p****d of having doctors keep referring to his accident in a passive sense and advising attending a fall prevention seminar. As he said, he could have had his accident at any age, his age was irrelevant to the accident.
Of course for disabled people (of any age) who are prone to fall easily, especially in the home, then there are strategies they can implement to reduce the risk. But most of them are common sense anyway.
We live in an old farmhouse with narrow steep twisty staircases and we have inflexible rules about not going up or down them bare foot or in socks/tights, all slippers and house shoes have rigid rubber soles, no slipper socks, or felt soled slippers. The only person to slip on them, in 22 years, was DGD, quite recently, when she tried to come down them in socks. Fortunately ground floor ceilings are low so the stairs are shorter than most and because they twist, it is very difficult to fall all the way down, she slipped three steps and then bumped into a wall.
I also invariably hold the bannister coming down any stairs and that applies to DGC if I am in charge - and I started to do that decades ago as the result of a safety talk at work. Nothing to do with age.
