Hi folks, I'm going to be honest here and say that I was sticky beaking into someone else's information. It didn't appear to be anything important - just some instructions to put together something. What is the best way to search these terms to get the most accurate answer? Alternately maybe you can assist in my query by attempting to figure out what the following words might be related to: atmospheric pressure, air, electric, filter I have my suspicions but I don't want to jump to conclusions at this stage. Last week I jumped to conclusions and I completely seized up and I fear that the more I can't function properly the more chance my suspicions will come true. I've tried getting into yoga to calm my nerves but that's another story. - Mr Suckarupparar
