Economists like to frame everything in terms of economics. One fairly hot topic these days is “health capital”, a stock into which we invest (by avoiding disease, eating well, exercising, and so forth) and which later pays a return (more success in school, higher wages, and what have you). Doug Almond’s fascinating paper about Ramadan is one demonstration of how big these returns can be: a small change in in utero nutrition can have massive effects on eventual physical and mental health, and impact eventual wealth as well. Health capital will also depreciate over time if you don’t maintain it: if you want to stay healthy you have to keep eating well and exercising.
When I go to the developing world to collect data, the cost of maintaining my health capital goes way up. It’s often difficult to find space or time to exercise, and depreciation (from pollution, water-borne illnesses, stress, excessive UV radiation, etc.) is so high that it often feels like I’m actively spending out of the principal of my endowment. Eight months collecting data in Malawi? That’ll be 5% of your overall health, please.
I’m sure I’m not unique in this problem: most people lose access to their preferred diets or exercise regimens for various reasons at some point, and being short of the time, space, or equipment needed for a workout is a common complaint. I’ve never had much in the way of a solution to this problem before, but this NYT piece points to a new workout that takes only seven minutes – and is summarized in a single nifty diagram.
A seven minute miracle workout is no surprise: I have various friends who swear by at least half a dozen different magic workouts between them. The unexpected thing here is that this one appears to be based on (some) actual science. The linked article is a review, but references previous research that not only suggests their approach may work, but actually appears to test it directly.*
I plan to try this out during my next trip to Africa – tentatively scheduled for mid-June.
