I agree with that, I disagree with the divide into 3 more than into 5.

Let's see, I concede the 24 hours of a day, or the 9 muses. But 60 minutes or second divide by 3 or 5 with no problem. 30 days for a month, again divide 3-5. Many things are seven. We also have 4 directions. Many things come in pairs. There are flowers with 5 based corolles and with 3 based one, so it's a tie here. I agree insects have 6 legs, so divide by 3. But other animals have numbers not based in 3 or 5.
