    I like to listen to your pod casts especially on labs and medications. I know that you have them categorized that way but is there a way that you can just play all so I can continuously listen while driving instead of having to go back and press play every couple of minutes once one is done?

      Thank you so much! Love hearing from podcast listeners. The best way to do this would be to go to the PODCAST tab on NRSNG and simply listen from there. Or to listen within iTunes.
