Ok, explain it to him this way.
The company goes to the beach to harvest the sand. They ship it in a hot/cold truck to the packaging plant (hot/cold) in there too. Then it sits on a shelf in the ware house (hot/cold) there too, then it gets put on another truck (you get the point here) and shipped to a distribution point or even the LFS
, then it sits on the shelf (remember this part?) until some one decides to purchase it.....
Oh, I think I forgot to add something about Oxygen and circulation....just add that to the ().....LOL.
Think you can convince him now?
