Nocturnal Emissions

Question: Is there anything that wakes you up as instantly as entering a recently vilified elevator on your way into work?

I don't know how faux-burled wood panels contains the stank so well but nothing smacks you like the linger of odorous passengers past. Honestly, what do you always notice when walking into a space - tooteledge. BO a distant second. Third, carnival food.

So, why don't nocturnal emissions wake you up? Not on the way out, but once they hit your nose. There is less room for the gas to dissipate and the path of least resistance for escape is right up past your face. It seems we would be exposed to an even more direct blast. I admit I am certainly more tolerant of my own making, but with so many people sharing beds it seems it would be a problem.

I assume we can answer this with science. My hypothesis is that we (early humans) used to wake up to our own toots to varying degrees and those that were less sensitive were more rested for the hunt and therefore killed more animals and got more and higher quality chicks and thus night toot sensitivity was eventually breed out of our collective human race.

This probably won't be answered definitively until we find the Missing Link.
