Klement on Investing 1 implied HN point 16 Feb 26
  1. Heat waves are already interfering with people’s ability to work. They’re even pushing households in traditionally cool climates to install air conditioning.
  2. Sick leave rises as heat waves lengthen, and people with circulatory problems are particularly likely to fall ill. Outdoor occupations like transport, logistics, agriculture, and construction are hit hardest.
  3. A single heat wave causes measurable lost wages and higher health costs, and while the GDP impact per event may seem small, repeated and worsening heat waves mean investing in adaptation (like cooling) is needed to limit future economic and health losses.

Vinay Prasad's Observations and Thoughts 164 implied HN points 13 Oct 24
  1. Closing schools for long periods during COVID-19 was a mistake. Some countries didn't close schools and found that kids were not at high risk, which should have guided decisions.

  3. The COVID-19 pandemic impacted poorer communities much more than wealthier ones. There needs to be more open discussions and debates to improve understanding about pandemic responses and their effects.
Weight and Healthcare 279 implied HN points 01 Jun 22
  1. Comparing smoking to being higher weight is not a fair comparison because they are different in terms of behaviors, interventions, and health impacts.
  2. Smoking and being higher weight are not directly comparable because body size is not a behavior like smoking, and the health implications differ significantly.
  3. Shaming fat people to be thin is not the same as shaming smokers to quit, as they are different issues with unique complexities and considerations.
