The enemy

Wouldnt it be nice if we really could save time?

Its a slow Wednesday today. Not much I really HAVE to do. Ill just put a couple of hours in the bank for next Monday, when things will be really hectic


When we talk about the length of a journey, are we talking about the time taken or the distance covered? Or are we indifferent, taking these to be freely interchangeable?

Transport schemes are usually appraised by reference to how much time the new motorway etc will save. Some of the knottier conceptual problems of this approach might in fact disappear if the appraisal concentrated on the extra distance gained

I heard somewhere that man has, over his entire history, spent about the same overall, constant proportion of his time in travelling. I wonder if this is true for women too? The latest UK figures show that the average woman travels only 3/4 as far as the average man (6,300 v 8,200 miles a year). But does she spend less time doing this, or does she just travel more slowly?

Years ago, during the Thatcher recession of the 1980s, there was a youth unemployment scheme called YOPS which paid participants a flat £23 a week. As someone charged with making comparisons of the relative earnings of males & females I was shocked to find that the difference in earnings appeared even among these 16 year-olds. But how? Turned out the the only extra you could claim was for essential travel to work. So girls either worked closer to home or were more likely to get free lifts. Or boys were more likely to make false claims
