I just got my mom home from the hospital (age 86) and with no one to help me, don'tcha know I come down with flu. I keep running to the bathroom, for various reasons. I'll spare you the details cause I'm not here to burden you with my problems, I just wanted to share this... With a temp of 100.2 and chills that are very uncharacteristic for me nothing and i mean NOTHING will get or keep me warm, except my AMK heatsheet! Thank God, and who ever came up with this modern marvel. The only thing better is if every drug store on every corner of America stocked them and they ought to. If you gotta be sick I sincerely hope you have on too.
