Sensitive to the touch?

This post was inspired by today's lecture about touch and nerve concentration. I remembered a game that started to circulate around 2011, the elbow lick game. where you would walk up behind a stranger and try to lick there elbow without them feeling it. Absurd I know but it was definitely amusing to try and accomplish. I guess the game was brought up to test the fact that callused areas of skin have less nerve concentration just like we discussed in class. The video attached is just an example of how the game was played, its pretty funny but also gross. I think the fact that they used distracted targets also says something but i also feel most of the responses were based on other factors such as peripheral vision and the reaction of others.
