Finally starting to get this health prevention stuff

So I met with Prof Chu again, the HBS professor I have been meeting with who made a few very convincing points about health prevention and economic decision making. The interesting thing is that human beings can be both extremely rational yet also extremely irrational. Rational when for example, deciding between planting cassava and potatoes as a farmer in Burundi and irrational when making health prevention decisions. For instance, we are very irrational in changing our behavior when the doctor tells us that we shouldn’t eat that fifteenth donut because of pre-diabetes and hypertension. Yet we are also irrational when for example women decide to wear high heeled shoes which kill your feet but are “fashionable”. Is there a way that our irrationalities could actually cancel one another out in a productive, health improving way? Prof Chu’s belief is that it can in a sustainable way. His current project between HBS and Harvard School of Public Health is trying to figure out some projects that would do exactly this.
