The Economics of Gym-Going, Part 2
From a reader named Laura Brown:
Read More »I recently joined a gym in a low-income part of Baltimore. For $10 a month, a person has unlimited access to the equipment — including treadmills that have individual televisions with about 20 different channels. For $19.99 a month, they have unlimited access as well as unlimited guest privileges. I’ve only been to the gym twice since I signed up, but both times (in the evening), the gym has been almost to capacity. However, despite the fact that it is almost impossible to find an open treadmill, many patrons don’t seem to be there to workout — most of them are obese, and the majority of the treadmills seem to run on the minimum speed settings — .5 mph — not fast enough for anyone to even break a sweat. I was pondering this yesterday during my jog, and it occurred to me that it is entirely possible that many of these people are using a gym membership (and the subsequent treadmill-television access) as a substitute for cable.

A new study finds that unemployment “increases the risk of premature mortality by 63 percent.” Eran Shor, one of the study’s authors, believes there’s a causal relationship: “In past research on the topic, Shor said it was hard to distinguish whether pre-existing health conditions, such as diabetes or heart problems, or behaviors such as smoking, drinking or drug use, lead to both unemployment and a greater risk of death. In the new study, controls were included to account for those factors.” Read More »
How Richard Feynman Thought
I am fascinated by how we can improve our thinking and problem solving and enjoy learning about and from masters of those arts. My interest was therefore caught by the advice on thinking given in a review of Quantum Man: Richard Feynman’s Life in Science. The reviewer, George Johnson, writes:
Read More »This triumph came early in his [Feynman’s] career. His later thinking (about solid-state physics, for example, or quantum cosmology) was just as original. Maybe sometimes too original, Krauss suggests. Science usually proceeds by building on what came before. The maverick in Feynman kept him from accepting even the most established ideas until he had torn them apart and reassembled the pieces. That led to a deeper understanding, but his time might have been better spent at the cutting edge…“He continued to push physics forward as few modern scientists have,” Krauss [the biographer] writes, “but he tended to lead from the rear or, at best, from a side flank.”
