     Personal computers and the Internet give people new choices about how to spend their time.
Some may use this freedom to share less time with certain friends or family members, but new
technology will also let them stay in closer touch with those they care most about. I know this from
personal experience.
     E-mail makes it easy to work at home, which is where I now spend most weekends and evenings.
My working hours aren't necessarily much shorter than they once were but I spend fewer of them at
the office.    This lets me share more time with my young daughter than I might have if she'd been
born before electronic mail became such a practical tool.
     The Internet also makes it easy to share thoughts with a group of friends. Say you do something
fun see a great movie perhaps-and there are four or five friends who might want to hear about it. If
you call each one, you may tire of telling the story.
      With E-mail, you just write one note about your experience, at your convenience, and address it
to all the friends you think might be interested. They can read your message when they have time, and
read only as much as they want to. They can reply at their convenience, and you can read what they
have to say at your convenience.
      E-mail is also an inexpensive way stay in close touch with people who live far away. More than
a few parents use E-mail to keep in touch, even daily touch, with their children off at college.
     We just have to keep in mind that computers and the Internet offer another way ofstaying in touch.
 They don't take the place of any of the old ways.

     Dr David Weeks has spent years studying these so-called "Superyoung" people. Now the
reporter(R) is interviewing Dr Weeks(DW).
     R: Dr Weeks, could you start by telling us exactly what you mean by the expression "Superyoung"?
     DW: Yes, well, I mean a lucky group of people who actually look and feel as much as 18 years
younger than they really are.
     R: Is looking younger than our age just a question of our genes?
      DW: Well, of course it's one of the important things. But we have many other things to think about.
My study has shown, for example, that a happy life is quite important. They often have friendships with
people younger than themselves too.
      R: And do the "Superyoung" have a lot of children?
      DW: No, in fact the opposite. Our study showed that 15% of the "Superyoung" don't have children
at all and those that have children usually have small families, one or two children at most.
      R: Is lifestyle important?
      DW: Yes, the "Superyoung" usually sleep very well and have usual or even low blood pressure. Our
study showed that they travel more often and when they do travel they often travel further. Generally
speaking, they are also people who read more and watch less TV than the rest of us.
     R: And do they do a lot of exercise or sport?
      DW: Yes, in fact we found that they are the kind of people who prefer to do sport rather than watch
sport. A strange fact we discovered is that they prefer the sports one person does such as swimming or
walking to playing team sports such as football.
