@edgarblythe,
When my poor old late FIL had an appointment for a pedicure, he decided to wash his feet before going, so he propped himself up, stuck one foot in the sink and promptly fell and hit his head. Blood on the brain. He was in hospital for 3 months and they wouldn't release him to his wife because they were both over 90 and she'd already broken a wrist twice and then a hip.
I've never understood why he didn't just sit on the edge of the bathtub.
Go for a pedicure. They also wash your feet!
