I have often benefited from recommendations for Things I Didn't Know I Wanted.
Given that Less Wrong is a community of unusually intelligent, critical, and self-improvement-focused people, I suspect we can generate a pretty helpful thread of product recommendations — perhaps even a monthly thread of product recommendations.
Rules:
- Post one product your recommend per comment, so they can be discussed and voted on independently.
- Provide a link for purchasing the product.
- No books, movies, TV, games, or music. (These should go in other threads, like this one or this one.)
The human ear has not previously been under selection pressure to accommodate extended periods of stoppage. Plugging up or cover ears for significant fractions of the day on a regular basis is out-of-spec use of the human body and may have consequences including infections and skin irritation.
Just be careful and talk to a pediatrician before applying this solution to children.
The human ear has also not previously been under selection pressure to accommodate constant noise pollution. Not plugging up or covering the ears (or abandoning civilisation) is also out-of-spec use of the human body and has consequences including stress and damaged hearing.
(Apply evolutionary reasoning consistently!)
