So it turns out that nose picking is, besides being life's reward for
failing to connect with other members of your group, a strategy for
optimizing the diversity of your microbiome. So if you are sharing
spit and breath with others then no need to diversify your own
microbiome, but spend too
much time alone and you will gravitate
toward nasal mining.
Nature doesn't probably do stuff by mistake so, guessing that there
have been lonely people around for a long time, there probably
might be some microbiological advantage to that too, thus open
booger, an opportunity to share breath, blood and boogers with
other lonely, ostracized people.
There's nothing like indulging in a few boogers and ostracism at the
end of a long day of not talking to people and having to pretend you
are happy at the bottom of the hydrodynamic microbiological air-
economical totem pole. Now you can use the leverage of the
Internet to ramp up your microbiological loneliness game.
Share boogers with other social pariahs based on a scientific profile
of your boogers's biome, thus optimizing whatever benefits nature
must see in imposing this fate on you and the other losers.
