Aristotle: Friends Essential For a Life Well-Lived…But ARE They – Really?

Comment: 

Studies show that having a good network of friends contributes to improved health, wellbeing and longevity. However, Aristotle lived and taught his philosophy prior to Christ coming into the world, so, doesn’t that make a difference?  Surely Faith and Family suffices to make us healthy and happy into old age?  I once met a young person – Edward – who said he didn’t have any friends. In further discussion, it turned out that he really meant there was nobody outside of his immediate family whom  he truly trusted.  In his case, Faith and Family seemed sufficient, or so he argued, to see him through life.  So, who’s right – Aristotle, or Edward?
