idk if yr in the states, i do work from home stuff from a company that outsources technical work and customer support for insurance companies or the like, its not fancy and doesnt pay more than most basic jobs but it does cover bills.
not documentary movies but ive kinda gotten into a rabbit hole of educational/informative youtube channels, a few quick ones: Animalogic (you guessed it, short vids abt the science of animals!) Journey to the microcosmos (an upclose and personal look at the world in front of our eyes that we never see), toldinstone (slice of life roman history), vsauce (arguably the best 'edutainment' channel... or is it?)
Do you have any animals of your own?
