Being a 40+ wheezing old knacker, it does annoy me having to run past (not after) the fairer sex half my age. I'm told it's all about physiology, whatever that may mean...........
I think there was something about a civvy copper dog handler who got binned because he didn't make the grade but his female counter-part sailed through, despite being many minutes behind. He went to a tribunal etc and it squared away in his favour. It may well be 'folk lore' though.
