From a social point of view, such behavior has not been controlled in time, so that the elderly have listened to the nonsense of these people. In today's society, people actually admire health care products very much, and even think that health care products are a panacea that can make people live longer. Those who sell health care products are often aimed at the elderly who are lonely. They will get on well with these old people at first and hold some lectures slowly. For example, attending lectures and taking eggs and other similar activities will attract many people's attention. The prices of these health care products are not low, and even all the savings of the elderly will be spent, but the elderly are still willing to buy them. This is because these salespeople talk about the efficacy of health care products, and the actual efficacy is only auxiliary. If we get enough nutrients in our daily life, these health care products will not have much effect.
For children, there is not much time with their parents in daily life, so parents will find daily life boring. They are more willing to trust those salespeople who approach them voluntarily. After all, I can take care of myself, and my children are too busy and tired in their daily lives. When they have their own children and families, they will pay more attention to this and care less about their parents.
If more social control can be implemented, such things will be reduced. If children can give more care, the elderly will be happier and will not do such seemingly funny things.
