Coop, my man... let me give you a gift today. It's a very important gift, one that I have learned to use myself from time to time...
Now, don't put anything into the bag- even your head. You might be tempted to do that, but that's not what I want for you. Just take the bag and put it up to your mouth and breathe in and out into the bag... that's it... deep cleansing breathes! In... hold it... hold it... out... keep it out... now in again, deeply... hold it... you get the picture.
