As a granddaughter, what gift should the elderly give for their birthday?

As granddaughters, we can give the elderly the following gifts on their birthdays:

Tea: Choose some tea that is beneficial to the elderly, and grandparents can drink it. But when choosing tea, you should choose tea with good taste and give it to them;

Electronic sphygmomanometer: the blood pressure of the elderly will be more or less abnormal every year. We can choose electronic sphygmomanometer to help them measure and record blood pressure, which is a good gift.

Waist Massager: When grandparents are old, it is inevitable that they will have backache. We will buy them a small waist massager, and it is good to massage their bodies at ordinary times.

Calcium tablets: Most elderly people lack calcium. Choose some good quality calcium tablets as birthday gifts for grandparents. Calcium tablets are not only beneficial to the body and joints of the elderly, but also help to prevent hypertension.

Clothes and shoes: Old people are thrifty and unwilling to buy new clothes and shoes. When grandparents are alive, we can choose some suitable clothes and shoes for them as birthday gifts.

Radio: People like to listen to some radio and news when they are old. We can buy a video recorder to listen to the news and weather forecast, which is also a good birthday present.

Mobile phones: Although they are all smart phones now, maybe grandparents are old and don't know how to use them. We can choose a suitable mobile phone for them to use, so as to contact at ordinary times.
