In the passage it says that there are many ways to "network" with people. But because of these networks it can cause many negative affects that can spread to other people. Many of the ways is through sex, obesity, smoking, drinking, and suicide. It says that these can be contagious and spread to other people even indirectly. From my point of view I find that obesity can be contagious. It says you can get fat from your friend's friend without ever meeting them. The passage about suicide being contagious because of the "idea" of it makes sense though. From my experience, I attended my friend funeral because he took his own life. It never made sense because he was all set to go to college but not long after we all graduated from High school, he gave up. At the funeral everyone was very sad and the idea of our friend taking his life can be contagious. But if we just think of all of the good times ands how glad we were to have him in our lives then maybe we can just appreciate our life a little more. I think that group suicides is the stupidest thing ever. Why would anyone be sucked into that because of an idea?
I don't have a "network" as far as I know but at least I try consciously to not let other people influence me on what they do. Sure if they have good habits like my friends love eating vegetables, it makes me want to eat more vegetables too. I will only copy good habits not the bad habits. Even though there could be a new "norm" that could affect me, it will just happen because teenagers are young and are just trying to find themselves and wanting to fit in with people to make friends. That's what I think about the sex network one. Like the little 6th graders just had sex with older guys because they thought it was "cool" or "norm" at the time. Like maybe they were competing how many sex partners they can get. The "network" is interesting because it can affect us indirectly at any time.
