The post, which is an AI-assisted teaser for longer manually written articles, emphasizes that the goal is not easy review but building strength so that previously hard material becomes easy.", "body_md": "# Spaced repetition is progressive overload for your brain.\n\n*(Note: This is an AI-assisted teaser for my prior manual writing.
