Seems that the British male is less interested in bonking his partner than in the past. As to possible explanations:
Cooper, who is professor of organisational psychology and health at Lancaster University, also blamed Britain\’s culture of long working hours. \’Britain\’s work culture has gone from 9 to 5 to extremely long hours, which makes for a very stressful life,\’ he said. \’Stress can be cumulative, which means eventually people can find it impossible to switch off and relax.\’
I think we can put that to one side. Average working hours have been declining for men for more than a century. You know, this evidence thing….
