Bad habits.

壞習慣

Excessive Screen Time

過多的看屏幕時間

Too much screen time can hurt your eyes and your brain. And your relationships. If you always take your phone with you to the bathroom, make a conscious effort to leave it in another room. Or read anactual paper book on occasion.

過多的看屏幕時間會傷害你的眼睛和大腦，以及你的人際關系。如果你總是帶著手機去衛生間，那就有意識地把手機留在其他房間里。或者偶爾讀一本實體紙質書。

Fidgeting

坐立不安

While many babies can't sit still, some grownup shave the same problem. Extreme fidgeting is a possible symptom of several conditions, including attention deficit hyperactivity disorder (ADHD), bipolar disorder and Tourette's syndrome. Professional help is necessary in those cases.

許多嬰兒不能安靜地坐著，然而一些成年人也有相同的問題。極度坐立不安是幾個不正常情況的潛在癥狀，包括注意力缺乏多動癥(ADHD)、躁郁癥以及圖雷特穢語抽動綜合癥。這些情況下，專業幫助是必要的。

【知識點講解】

hyperactivity n.活動過度；極度活躍

例句：

Given the effects of cocaine on people, hyperactivity may seem like a fairly obvious reaction.

我們已經知道，人若是服用了可卡因，最明顯的表現可能是極度活躍。
