Allah and Yawning
Narrated Abu Huraira: The Prophet said, "Allah likes sneezing and dislikes yawning, so if someone sneezes and then praises Allah, then it is obligatory on every Muslim who heard him, to say: May Allah be merciful to you. But as regards yawning, it is from Satan, so one must try one's best to stop it, if one says 'Ha' when yawning, Satan will laugh at him." - Hadith - Bukhari Volume 8, Book 73, Number 242
So according to Muhammad, God likes sneezing but it's Satan, the Devil, that makes you yawn. It's got nothing to do with being tired, it's demonic possession. So we can see why both the United States and Indonesia have been governed so badly. Maybe Donald Trump is wrong, Obama might be a Devil Worshipper, not a Muslim.
This could also explain the incredible spiritual downfall of the Roman Catholic Church.
And Prince Harry … that's not exactly a surprise
People in the ancient world weren't stupid. As long ago as 400BC, Hippocrates thought yawning was caused by a large quantity of air that has accumulated inside the body and ascends all at once, lifting and opening the mouth like a lever so it can exit easily. He compared yawns to large quantities of steam that escape from cauldrons when water boils. That wasn't correct but it was a lot smarter than Muhammad's superstitious nonsense.
