Analysis
They have taken precautions before everything comes too late. As a result, only a few accidents may happen. They were really enthusiastic.
We progress in cleaning a place in a period during which no elderly are doing exercises or they are in other places. For instance, we will clean the corridor when the elders are having their meals. The floor of the corridor will be dried when they have finished their meals.
In winter, they will take a tertian bath, as they are afraid of coldness. And ,we turn on the stove to raise the room temperature. These can insure their health. In summer, they will take a bath every day. Besides, no matter which season it is, we apply the moisturizers on their skin, as their skin is very dry, even if it is a wet day. They will scratch their skin which may be damaged. Finally , this may lead to bacterial infection, and a number of problems will occur.
They consult The Union of The Fire Services Department Ambulancemen for methods which are combined with their own to form a rescuing mechanism.
As shown above, the steps are clear and I believe when an elderly suddenly swoons, he/she can still survive.
Nowadays, a number of elderly living here have Alzheimer Disease or mental disorders, that can't be changed. We expect the normal elderly can accept this and will teach the abnormal one. Our role is passive all along.
