Answer:
grandparents/elderly person in the family and ask about their experience before the telecommunication days are as follows:
Explanation:
My grandmother is nearly 75 years “ youngish ”. Yes, she doesn’t truly like being sounded off as “ old ”, and she, of course, has explanations for that. In fact, indeed at this 75 years of age, she enough much has all her teeth, and she veritably infrequently uses any spectacles unless she has to pore some really fine imprint. Of course, she occasionally complains about the joint pains in her core, but that hardly at all stops her from stepping for 40 years youthful and picking up her effects suited without any support from others around her.
Anyway, I enjoy speaking to my grandmother, firstly because she's veritably quiet-spoken. In fact, I've roughly ever pioneer her to be awkward like other senior people of her time. either, I also enjoy speaking to her because she shares a lot of hilarious and fascinating stories from her youth and adolescent days.
