Loved your question, Learnt a lot.. pleasant surprise to see some familiar qns being referred to on the article (kinda like Candid Camera)
sorry, could not reply sooner, we hotline junkies weren't up at that 3.00 a.m (although i've once been up answering qns from half way across the world, sitting in India! )

Loved your question and loved the NPR article - thanks!

Come again!
