obesity, 1st Visible sign of the general breakdown of our health. as acid rain had trees die back in the ’80′s. Trees that lived to 500 years when we first came to this land now are lucky to survive for a hundred years in the city. Most die from a disease, fungus carried by saws and clogged pores. We are as sick as the distance we live from nature’s green belts, compounded by the trail of our toxic exhaust

Funny how quick people think about Facebook when the talk is about friends.

@Ikar1 perhaps the barrier of feeling personal threaten should be solved before all the mirror neurons enter the game. If you smile in front of a baby it smiles as far as I tested. It detects eyes+your teeth and reflects. There is a video in youtube called “monkey see monkey do” that explains it. If I say in my office, family or friends “I want to tell you something… ” while smiling and self interrupting me they do return a smile. Of course that the stress inhibits that.

Does it mean that if get fat Facebook friends you will get fat too?
How about other diseases and addictions? Do they spread by text messages?
How positive qualitys spread relatively to negative?

@chuckinator13 You …
@chuckinator13 You are talking about “how sould it be”, not “what it is”. My point is that Christakis took an example that doesn’t look to be very… realistic? I guess that the fact is that, in most countries today, nobody replies with a smile.

@vraciudude Take …
@vraciudude Take into account, the use of electronic communication, especially the use of texting as a substitute for personal interaction. The use of emoticons suddenly serves as a direct link to our emotions and how we feel about certain situations. It is as if we have neglected the need of personal communication and found a way to replace it by electronic communication. Facebook, texting, twitter, email etc all fall under this.

@neoflyboy In that case I smile because he looks funny or the show is actually good, not for a kind of neuronal reflex from his own laugh. Is not the same if an unknown guy smiles you in the subway.
