Our furnace kicked in, so i guess it's cool weather where i'm at

this furnace hasn't been on since March or sometime like that, ewww i'm just now thinking of the air quality, what sort of insane looking micro-organisms are floating around being inhaled through the nose and so on .... that is why i shy away from learning science stuff, it's unnerving, so i shall soon wash my hands before getting back to Bernhard's Concrete, as it's always a good idea to have clean hands while reading a physical copy.
