Can you read through my arguments please and offer some criticisms on my writing?

I like the essay. Some simple corrections In the last paragraph ... It should read "It was she who found the time... You don't need a comma after "she" The last sentence should begin "Older people have more experience in life, so their advice will be ..... I would take out the sentences beginning with "Of course they are weaker.......duty of looking after and standing .......weakest in our society." They don't seem to fit everything else in your essay. The example of your grandmother is excellent. Good job!
