Thanks again! I'm sure you understand it.

I am still trying to cope with the difference between magnetism and gravity.

The only thing I know about gravity is it keeps me on the ground, and it keeps trees growing straight up.

Trees have hormones called auxins that tell whether to grow straight up or sideways. If the top gets broken out of a tree, a branch takes over and finishes the job by growing straight up. Auxins somehow sense gravity and sunlight, and almost never fail unless a Japanese Banzai artist gets ahold of the tree.

Magnetism keeps refrigerator magnets from falling on the floor.

At least I can understand that.
