午餐：
鸡沙拉 @ 老麦
晚餐：
叉鸡+饭1碗+冬瓜盅
夜宵：
脱脂奶一杯
低脂芝士一片
饼干两包
果仁类
晚上完成了30个塘，到了第12个时觉得饿和无力，应该是血糖不够，但有点奇怪，
因为2小时前吃晚饭，理应没有这个问题，可能是中午吃不够，也有可能是休息不
够，又或是游泳太密（周一油过）。其间想放弃，但最后坚持到底。回家路上想吃
很多东西，如寿司、面、粥等等，但都控制了这些欲望，力保不失。要继续努力。

Bounded Rationality

What is Bounded Rationality?
The question of bounded rationality is: How do real people make decisions when time is limited, information costly, and the future uncertain? For many economists, the answer is that people behave as if they optimized under constraints, such as information costs. For many psychologists, in contrast, the answer is that people commit reasoning fallacies due to limited cognitive capacities. These two visions of the nature of bounded rationality make an odd couple, one promoting rationality, the other irrationality. In this lecture, I discuss an alternative view based on Herbert Simon's vision of bounded rationality: the study of fast and frugal heuristics. The heuristics in the "adaptive toolbox" are anchored in the mind and the environment. They are embodied in the sense that they can exploit capacities of the human mind (such as recognition memory), which allows judgments to be quick. They are anchored in the environment in the sense that they can exploit statistical or social structures (such as signal-noise ratio or trust), which allows people to ignore information - less is more. The rationality of heuristics is ecological, not logical.
