I am so so so sleeeepy........... and it's only Tuesday!

New piece of fact learnt today at Obstetric lectures. Have you ever tried shitting with your mouth open? That is supposedly a difficult thing to do. To be more exact, you need to have your epiglottis (the structure that blocks off your trachea when u swallow/eat) closed so that the pressure from straining is maintained and helps u do ur shit. If u can shit with your mouth open, u are probably not breathing.

My friends and I were pondering over this fact at the dinner table. Imagine a table of pple mentally visualizing if they could strain with their mouth open at the same time.

Thank god for 'tidbits' like that during lectures. Helps to reduce the number of times one nods off.
