As we hit middle age, we often start to notice that our memory and mental clarity are not what they used to be.
人到中年，我们通常会开始发觉自己的记忆力和脑力不如从前。
We suddenly can't remember where we put the keys just a moment ago, or an old acquaintance's name, or the name of an old band we used to love.
我们会突然忘记自己把刚放下的钥匙放哪了，或想不起旧相识的名字或曾经非常喜欢乐队的名字。
This loss of mental focus can potentially have a bad impact on our professional, social, and personal well-being.
这种心智上注意力的缺失可能会对我们的工作、社交以及个人生活产生不好的影响。
Neuroscientists are increasingly showing that there's actually a lot that can be done.
神经学家不断表明很多方法可以帮助改善这一情况。
It turns out that the brain needs exercise in much the same way our muscles do, and the right mental workouts can significantly improve our basic cognitive functions.
事实上，大脑和肌肉一样需要锻炼，而且正确的锻炼方式可以大幅提高大脑的认知功能。
Thinking is essentially a process of making neural connections in the brain.
思考从本质上来说是大脑中神经元之间发生联系的活动。
To a certain extent, our ability to excel in making the neural connections that drive intelligence is inherited.
决定人们智力高低的这种神经联系在一定程度上由遗传决定。
However, because these connections are made through effort and practice, scientists believe that intelligence can expand and fluctuate according to mental effort.
然而，由于这种联系同时也是通过努力和练习实现的，科学家因此相信通过心智的练习，人们的智力水平可以得到提升或上下波动。
Now, a new San Francisco web-based company has taken a further step and developed the first "brain training program", Lumosity, to actually help us improve and regain our mental sharpness.
基于这一理论，旧金山一家新创立的网络公司采取了进一步行动，开发了一个名为Lumosity的“益智游戏”，旨在提高或恢复我们的思维敏捷性。
Lumosity, is far more than an online place to exercise our mental skills.
Lumosity不仅仅是一个益智平台，
The program keeps track of our progress and provides detailed feedback on our performance and improvement.
这款软件记录我们取得的进步并对我们的成绩和进步给出详细反馈。
Most importantly, it constantly modifies and enhances the games we play to build on the strengths we are developing—much like an effective exercise routine requires us to increase resistance and vary our muscle use.
最重要的是，与日常的健身锻炼增强人体韧性和肌肉多种拉伸类似，它通过对游戏不断更新和完善，巩固提高我们希望得到的能力。
