Original post

  • Key idea: A 2023 study finds that consistent sleep timing is more strongly associated with lower mortality risk than total sleep duration.
  • Discussion highlights: Commenters emphasized confounding factors (e.g., occupation, shift work) and cautioned against interpreting correlation as causation. One user credited magnesium supplementation for resolving stress-related insomnia.
  • Community sentiment: Supportive of sleep hygiene, but skeptical of overgeneralizing observational data. Interest in physiological mechanisms like magnesium’s role in nervous system regulation.

6. Sony deletes more movies from the accounts of people who ‘bought’ them (385 comments)

Original post

  • Key idea: Sony remotely removed purchased films from users’ digital libraries, reigniting criticism of digital ownership models.
  • Discussion highlights: Users demanded refunds or downloadable files, arguing that "buy" implies permanent access. Legal debates centered on whether digital licenses constitute fair contracts.

7. The kids with phones are alright (379 comments)

Original post

  • Key idea: Article argues against alarmist views of teens and smartphones, asserting that phones themselves aren’t harmful—addictive app design is the real issue.
  • Discussion highlights: Commenters agreed apps exploit attention through dark patterns, particularly affecting vulnerable youth. Analogies drawn to tobacco and gambling industries’ manipulation.
  • Community sentiment: Critical of social media platforms, not devices. Widespread support for regulating addictive design, especially for minors, while preserving tech access.

8. OnePlus halts operations in USA and Europe (334 comments)
