These are the types of things that get out of control and make my head hurt after awhile. Sometimes when I am in deep research for a post there is a bunch of stuff I am tracking and I am trying to reconcile some dates to events and whatnot, gets confusing.
I can already see why some people spend their lives on it.
When getting into this sort of study, I kinda get into a zone and can go many hours without stopping. Initially I prepared preliminary reading and resources for this study for a couple of months, then dove in when I had a break. It ended up being an intense three days of doing nothing else - incredibly exhilarating and fatiguing at the same time.
