Usually care more about the elderly, communicate with them more, and buy them more delicious food when you go home. If you have time, go through the medicine cabinet and look at the bedside table of the old man.

After they buy things, especially health care products and nutrients, they will put them on the bedside table. Read more books at ordinary times, and you can find problems in time.

As long as you spend enough money on the elderly, don't give more. Paying more is easy to be targeted by salesmen.
