You seem to be in denial although your point about correlation not meaning causation is well taken. However if we take the case of smoking we may say smoking does not cause cancer it only seems to be an ingredient which is found when people die of cancer. I mean technically correlation does not imply causation, but practically in some cases as the one the article is talking about it kinda does. Sure enough there might be something else which causes people to seek friends and that very same thing causes people to die earlier, however what we know is that having friends is a good thing and it seems they prolong your life. Now the way I formulated the last sentence it sounds like correlation but really it implies causation.
