Question from west
Hi Debra and the Internet community:
How long have grains been used as a microwavable therapeutic heating pad stuffing?
I’ve never seem to have heard of it before. Is this a recent development or an ‘old’ idea that’s been brought to modern times by reheating via microwaves?
Frankly it surprises me that grains are so good for retaining heat! 
Thank you.
Debra’s Answer
Readers, does anyone know the history of this?
