商务外围什么意思，>is procrastination genetic?
new research appearing in the social cognitive and affective neuroscience journal shows procrastination may be related to genes.
researchers from the university of bochum in germany focused on a single gene which creates an enzyme called tyrosine hydroxylase.德国波鸿大学的研究人员专注于研究一种可产生酪氨酸羟化酶的基因。
this gene helps regulate the production of dopamine — a chemical messenger that plays a role in brain processes such as attention, memory and motivation. the presence of dopamine is different from person to person.这种基因有助于调节多巴胺的产生，多巴胺是一种在注意力、记忆力和动机等脑活动中发挥作用的化学信使。多巴胺释放多寡因人而异。
researchers say this affects "cognitive flexibility". this is related to whether people can multi-task. those who cannot may be forced to make fewer decisions simultaneously.研究人员称，这会影响"认知灵活性"。这种灵活性关系到人们能否同时完成多重任务。不能同时完成多重任务的人不得不在同一时间内少做决定。
this, in turn, makes some people procrastinate or appear lazy. in other words, when people appear lazy, it may not be the fault of their genes.这就使得一些人做事拖沓或者看起来很懒。换句话说，当人们看起来很懒时，或许并非他们自己有错，而是基因"犯的错"。
