Now, this journey is a testament not just to you as individuals, but also to the families that surround you, because yourjourney began long before you got that first military haircut and put on white-over-grey.
You can either while away an hour-long train journey getting lost in a paperback, or alternatively you could bury your head in some absorbing prose on a screen two inches (4cm) wide.
The next time you're on yourjourney home - be it from work or from holidays - and you're bemoaning the long motorway drive, just think how much worse it would be without the 50-year-old stretch of highway.
