These are media and/or subject obsessions that have dominated large portions of my life, ranging from a year into lifetime interest. Some of them have expired and were, in nature, sporadic. Some of them have not.

• Orca whales
• German Shepherds
• Reading long books
• BBC Merlin (2014-2016; 2018-2019)
• Yuri on Ice (2016-2019)
• Mob Psycho 100 (2021-2022)
• Keanu Reeves filmography (2022-2023)

Other long term fixations are fixations that lasted six months or longer and have the potential to go on for longer, though some rest with them is recommended. They can also go dormant.

• Lord of the Rings, typically a 1-2 month period after finishing the trilogy
• Twin Peaks (2023-2024)
• Dungeon Meshi (2025)
