I'm 42 and I think a lot of people here would find it surprising that my life just 20-25 years ago was radically different than it is today. To give an example -- then, the only way to contact me when I was not at home was to leave a message with anyone who answered the phone at home. If nobody was home, tough luck, try back sometime you think someone would be home (ie: no answering machine, no cell phone). Email ...meh once a week when I'd go to the cyber cafe to browse the net, chat with strangers online ..etc. ...and if that is surprising, the more surprising thing is a lot of people still live this way in large parts of the world. There's always a long lead time between technology becoming available and becoming ubiquitous the world over.
