I really enjoyed this article on ESPN about the workouts of Chess Grandmasters.

The 1984 World Chess Championship was called off after five months and 48 games because defending champion Anatoly Karpov had lost 22 pounds. "He looked like death," grandmaster and commentator Maurice Ashley recalls.

Robert Sapolsky, who studies stress in primates at Stanford University, says a chess player can burn up to 6,000 calories a day while playing in a tournament, three times what an average person consumes in a day. Based on breathing rates (which triple during competition), blood pressure (which elevates) and muscle contractions before, during and after major tournaments, Sapolsky suggests that grandmasters' stress responses to chess are on par with what elite athletes experience.

Fascinating stuff. Makes me feel like I really need to improve my exercise routine.

It just hit me that it's week five of my batch. I need to sit down and figure out what I've completed. I originally wanted to ship something every three weeks, I wonder if I'm on track for that. Recurse Center has been a weird place compared to how I normally work.

This month has kind of sucked. You'll notice a half-finished homepage here, mainly because I relaunched my site in frustration. Lots of things are broken, but if there is something you particularly miss, please let me know by email or @icco on Twitter.
