I think Cherubim are children, and Seraphim are adults.

Stalagtites cling tight to the roof, was my mnemonic. I don't know the term for after tite has met mite and it's one thing from floor to ceiling (or ceiling to floor, depending, double ha ha) - maybe just plain Stalags? Oh, no, that's already taken.

I think that the Roman sinister didn't just mean left, but also evil and black and all that stuff we use sinister for. Dexter is certainly right and proper, not just right/not left. I think that is WHY the Roman word for left was sinister, because the superstition was already there. And yes, it's the devil thing that makes people in folk songs look over their left shoulder when about to do something evil... although in the Queen Eleanor case, it would have counted as justifiable.

Heart attacks shoot pain down your left arm because that is how the nerves grow, since the side of your heart with the nervous fibers is on the left. Strokes, however, will radiate pain according to where the stroke is, so a right-side stroke is felt on the left side of the body (not necessarily the headache, but the other affected parts), and a left-sided one on the right.

My Mom went through first through third grades with her left hand tied behind her back. She's still left-handed, but she writes with her right hand.
