Greetings! I just want to say one more thing about continuing to learn. I think it is a grave mistake to suppose that "we already know" anything, because stuff keeps changing all the time. An example: A beekeeper who works part time for the University was told he had to take a safety training course. He was moaning about it, saying he already knew what he needed to know. I reminded him about driving around with gas in an unmarked can (it said "blower" on it, written in magic marker). He says: Well, I know what's in it. So I say: All you have to do is put it in a red can that says Gasoline and you're fine. Suppose you get in an accident and that's splashed everywhere, who's gonna know what it is? Him: I don't get in accidents. Then I told him he would learn a lot about gloves, which is important, since beekeepers use a variety of chemicals. He says: I never wear gloves. Me: Not even handling coumaphos? Him: Nope. Just grab it with pliers. Me: Not even when you open the package? That's an organophosphate insecticide that comes wafting out of the package. Why not put on disposable rubber gloves? He says: I never wear gloves. Moral of the story: when you think you "already know it all" you better start listening. -- pb http://www.people.cornell.edu/pages/plb6/
