Mostly health stuff this week.

  1. A meta-analysis on resistance training and longevity1 found mortality benefits plateauing around 60 minutes of strength work per week. Less is more than zero. More than 60 is mostly social.
  2. The new GLP-1 long-term data2 is less interesting than the headlines suggest. Effect sizes are real, side effect profiles are real, and we still don't know what happens at year ten. Anyone telling you they do is selling something.
  3. A piece arguing that "step counts" are an arbitrary metric that survived because watches could measure them3. The author is right and also being a little smug about it.
