I used to heavily be into collecting video games. Hardcore. It became an obsession.
Most of the collection is long gone now - sold off to younger more obsessive collectors, but some things, like my obsession with playing Dr. Mario, will never go away.
From the NES to SNES then to N64 and currently on the portable 3DS, I rotate colored pills, Tetris-style, to eliminate red, blue and yellow viruses.
In my brain, when I sleep, I still am playing Dr. Mario. When I am gone, in my grave, I will still be playing Dr. Mario.
