Contemporary folklore and stereotypes that we are exposed to contribute to a lack of knowledge concerning native American fishing practices. Brumbach (1986:36) noted that "popular folklore emphasizes fertilizer value of the fish but seems vague about their consumption as food." Perhaps the stereotype of the "hunter/gatherer" among anthropologists similarly attenuated a focus on fishing, as the word "fishing" is not included in the phrase "hunting/gathering." Despite this fact, in some societies, the role of fishing may have been equal to or surpassed that of hunting and/or gathering. 
It's an incredibly powerful discipline to put in place a rule of thumb that deals have to be accretive within some [specific] period of time. At Citigroup, my rule of thumb is it has to be accretive within the first twelve months, in terms of EPS, and it has to reach our capital rate of return, which is over 20 percent return within three to four years. And it has to make sense both financially and strategically, which means it has to have at least as fast a growth rate as we expect from our businesses in general, which is 10 to 15 percent a year.
