Answer:
You will have someone to talk to so you can relieve your stress and feel happier, studies have shown that the more friends you have, the more social you will become, and the lesser depression or anxiety you will have !
I've always been taught that revising involves checking for spelling, punctuation, and grammar. Basically any kind of improvements. Is this one of those questions where you check all that apply? Revising also includes making sure you have stayed on topic and gives you the chance to remove things that may not really apply or add other things that may have been left out. It's where the writer truly polishes everything up.
I hope this helps.
