A study found that rotating seven specific scents daily for six months boosted elderly participants’ memory by 226%, as smell directly connects to the brain’s limbic system. Inspired by this, Mr. Y explored multi-scent diffusers but found current products limited. Believing the technology is simple enough, I plan to build a DIY multi-scent controller with AI guidance.

This essay reflects on Warren Buffett’s wisdom, inspired by his rule of never taking heavy positions in companies that might surprise him. The author argues that Buffett’s extraordinary longevity grants him unparalleled insight, making him a sage among “summer insects” who cannot comprehend ice. Cognitive blind spots, shaped more by objective conditions than intelligence, silently constrain our judgment. Buffett’s charity lunches are reframed as transactions for life-extendin

AI can write for you. But here's what it can't do: think for you. Paul Graham warns that as AI eliminates the need to write, humanity will split into "thinks" and "think-nots" — because writing isn't just communication, it's how ideas actually form. The cruel irony? The moment writing seems obsolete is exactly when it becomes your greatest competitive edge. Write, or be left behind.

Reading aloud develops language pattern recognition, which is crucial for fluency and natural expression. Humans process language in chunks or “patterns”, not word by word. Through repeated exposure, common sentence structures and collocations become automatic mental modules. Native speakers acquire these patterns unconsciously through massive input, forming intuition about what “sounds right”. Second-language learners lack this environment, but extensive reading aloud replic

Regular aloud reading transfers expressions from short-term to long-term memory, making them instinctive. Moreover, reading aloud cultivates a natural sense of rhythm and flow in language, which formal education rarely teaches. Lacking such training leads to awkward, unbalanced writing and poor expression, even in one’s native language. Thus, reading aloud builds fluency, intuition, and stylistic grace.

Reading aloud powerfully strengthens memory and comprehension. Fluent language use, testing success, and logical reasoning all depend on language memory. Reading aloud transforms understanding into memory through repetition and active engagement. Memory and comprehension reinforce each other: better memory enhances understanding, and deeper understanding improves memory. Thus, extensive reading aloud builds the mental foundation for fluency, logic, and efficient learning.
