I slipped on a 4 inch piece of marble between my bathroom and the wooden passage floor. It was wet but the marble is white.
I’m way younger than 73 but I hurt myself by doing a full splits. My undercarriage smashed into the floor,
I was just walking from the family bathroom to the lounge.
The point of my point:
You can do damage anywhere. At any time.
He will know when it’s not safe. That’s my 5 cents worth.
