A third potential explanation is that intelligence is about good decision-making. Every day, as we live our lives, we make decisions about our health: what, when, and how much to eat; how much exercise to take; how to look after ourselves if we have an illness; and so forth.
第三个可能的解释是，所谓智力就是良好的决策。我们每天生活中都要对我们的身体健康做出决定。这些决定包括我们吃什么、什么时候吃以及吃多少，进行多少锻炼，有了疾病如何照料自己以及等等其他问题。
