Have you seen any older people hurt at their home due to lack of home safety precautions by their children?

No. That question has a tone of concern that children are to blame for not doing home safety precautions....People are clever whether they are 2 years, 20, or 80+. Unless one is a rubber room with no furniture, there are ways to get hurt. Doing the best you can to provide a safe environment is important. Do not ignore signs that older parents are having balance or cognitive issues and be proactive.
