Can't remember life before mobiles? Chances are you'll also struggle to recall your home phone number and family birthdays.

不记得没有手机的日子了？可能你也记不清家里的电话号码和家人的生日了。

According to a survey released on Friday, the boom in mobiles and portable devices that store reams of personal information has created a generation incapable of memorizing simple things.

据上周五公布的一项调查，随着可存储大量私人信息的移动产品和便携设备的兴起，如今的人连最简单的事也记不住了。

A quarter of those polled said they couldn't remember their landline number, while two-thirds couldn't recall the birthdays of more than three friends or family members.

四分之一的受访者自称不记得家里的电话号码；三分之二的人最多能记得三个亲戚或朋友的生日。

The tech-savvy young fared worse than older people. The under-30s could remember fewer birthdays and numbers than the over-50s, according to the survey.

“精通科技”的年轻人在这方面可不如年龄较大的人。调查显示，30以下的年轻人能记得的生日和电话号码比50岁以上的人少。

Two-thirds said they relied on their phone or electronic organizer to remember key dates.

三分之二的受访者称，他们主要靠手机或电子记事本来帮助自己记一些重要的日子。

"People have more to remember these days and they are relying on technology more for their memory," said Ian Robertson, professor of psychology at Trinity College, Dublin.

都柏林圣三一学院的心理学教授伊恩·罗伯特森说：“如今人们记这些日子的手段越来越多，而且他们的记忆更为依赖科技手段。”

Researchers polled 3,000 people over the last two weeks in the survey for Puzzler Brain Trainer magazine.

此项为《智力训练》杂志开展的调查于上两周进行，共有3000人参与。
