What you've stumbled into when you go to look something up quickly in Wikipedia only to emerge 3 hours later having followed hundreds of links into myriad topics about which you never thought you would care. Like quicksand, its grip is unrelenting and the more one tries to extricate oneself, the more browser tabs one opens to continue down alternate paths. Usually starts out as a momentary tangent to try to dredge up memories of an old technology or company or natural disaster and quickly turns into an all-day waste of time. Not that learning is a waste of time, but you should really get back to work already. And close some of those tabs.
I only wanted to quickly look up this Senator, but I got stuck in wiksand and now I know all of the African countries by heart and the chemical make-up of capsaicin.
