english: And here, the idea is not that my weight gain is causing your weight gain, nor that I preferentially form a tie with you because you and I share the same body size, but rather that we share a common exposure to something, like a health club that makes us both lose weight at the same time.
non_english: Ovde nije ideja da moje dobijanje na težini uzrokuje vaše, niti da se ja vezujem za vas jer imamo sličnu građu, nego je ideja da delimo sličnu izloženost nečemu, kao npr zdravstvenom klubu, gde oboje u isto vreme gubimo na težini.
