So now I'm not wrong, I'm just off the mark to a subjective inflection of the word hard. Just when I thought you've topped yourself at entertaining me you drop this. Seriously, thank you. My afternoon has gone much quicker on a slow day at the office.
And the nice thing about having been in oil and gas for so long is I don't need to do any research because I know all about it already by working, attending trade shows, safety classes out the ass and such. I learned about this stuff years ago before it was trendy to google two weeks ago.
