OP (original post) topic, Bojko.
Since my Glucose Count is a constant battle for me, I think this is an excellent test for anyone to take. It may open an area unbeknownst to them that they'd be better knowing about.
High sugar levels, unchallenged for years, lead to eyesight degeneration and perhaps eventually to blindness as well as encouraging stroke.
It's not a game. Sugar is NOT a friend.
I'm VERY glad to hear your sugar levels were normal.
The only thing I remember about science was my teacher slicing carrots lengthwise to demonstrate the inside. They were old limp carrots he'd salvaged from his refrigerator and so it was funny when he flung them around to the students to examine instead of handing them. I guess it was easier that way.
He was a great guy who made science interesting and fun.
