Breath-Holding

Did you know that if you hold your breath for long enough whilst agitating the hairs on your arms, you will start to hallucinate sensations of flying?  This is from our evolutionary past in the "bird" stage, and is brought about through invoking the sensation of air rippling across your wings. 

Birds do not breathe, which is why you must hold your breath to experience the effect.

Mondays

The origin of the term 'Monday' is related to the praise of our closest genetic relatives - the monkey. Coined by Michael Jackson in 1988, the day was intended to be dedicated to special sessions devoting ourselves to the monkey god hanuman, who Jackson believed had been reincarnated into the body of his pet chimp Bubbles. 

There are no records of what the day was used for before this date.
