Freakonomics week ends with diminishing marginal utility and curing the world of diseases

Contrary the law of diminishing returns, or marginal utility, donuts do not decrease in pleasure as you continue to eat them.  They actually rise in pleasure.

So do skittles.  

After swimming the Freakanimicists decided to see if they could counteract the behaviors that spread disease and eradicate the dreaded blue, red, black, and yellow diseases. They succeeded at curing blue and black before camp ended. Well done Freakanimicists!!
