There are times when to plant underground tubers for instance and that is NOT when the moon is waxing. You want to make sure the moon is down.

Putting seedlings in the ground, transplanting anything that grows ABOVE ground is best done on a new moon or after, when the moon IS waxing.

Just like surgery of any kind; better not to do it on a full moon; more chances of bleeding or hemorrhage. Don't want to be castrating your pigs around then either.
And because you're a male, you'll never quite know the pull of a full moon on your menses and the cramps and hellacious bleeding that creates. You see, we can't measure some of these things. It's just a learned thing.

And I may be wrong about the prediction; but I have a right to call it if I feel like it.
After all, a good percentage of posts around here are predictions about the market, the future, the election process, gold and gas prices, etc....
