And divisible by three which is a number found throughout all physical creation and human history. Many people have fixated on the number three and its multiples. Tesla only rented hotel or boarding rooms with the number three or a multiple (333 was a favorite). He also did every daily thing three times: turn off the stove- check three times, lock the door- check three times and so on. I don't consider myself fixated on that number, but I always use its multiples in daily life- when a number is called for. When a story deserves 'claps' I give them in multiples of threes (except for 50 claps). And I check everything three times before I leave home. I think that's simply a wise, if superstitious, practice.

Perhaps I am a bit fanatical about it...
