Hmmmmm. Am I REALLY, REALLY wrong or does a 'disease' require a virus or bacteria as it's root cause. Nowadays just label something a 'disease' and you can scare the hell outta people and push whatever $hit product you want. PAD Peripheral Artery Disease. Nothing to do with virus or bacteria but it's a disease.
Oh well, what do I know. ;)
Ahhhh well. ;)
