   • 2013 July 19, Ian Sample, “Irregular bedtimes may affect children's brains”, in The Guardian Weekly, volume 189, number 6, page 34:

     Irregular bedtimes may disrupt healthy brain development in young children, according to a study of intelligence and sleeping habits.  ¶ Going to bed at a different time each night affected girls more than boys, but both fared worse on mental tasks than children who had a set bedtime, researchers found.

使用する際の注意点

• (all, every): The phrase beginning with each identifies a set of items wherein the words following each identify the individual elements by their shared characteristics. The phrase is grammatically singular in number, so if the phrase is the subject of a sentence, its verb is conjugated into a third-person singular form. Similarly, any pronouns that refer to the noun phrase are singular:

  Each candidate has 49 votes.

  Each voter must decide for herself.
