Brainstorm SUSPECTED REASONS here !

Hi Everyone!
Since we’re fortunate enough to live in a place and time that, freely, allows us to share information about anything worldwide.... why not use it to our advantage and try to figure out the underlying cause of our problem? The easiest and fastest way to do this is if everyone cooperated and shared their thoughts here. Please share any information you deem relevant to this condition, no matter how silly or absurd you might feel it is. You never know, we might just hit upon the key/keys to this puzzle that allows us to unlock the cure!
Thanks for sharing!
