Thanks for the explanations/examples, Bobo. As someone with an extensive background in the sciences, it was more of a rhetorical question... compounded by a healthy dose of sarcasm, which pretty much comes naturally for me (I often forget that people around here don't know me well enough yet to understand that more charming part of my personality)
They were very nice answers though, and I just wanted to say thanks both for your time and your input
