All those men who opt for a motorbike to increase the perception of their virility are sadly mistaken it seems. I read in the Daily Mirror (It was the only available thing in the waiting room, honest) today that the vibration of the motorbike saddle decreases male fertility. Or is it just that most men who own a motorbike are over the age of forty, in mid-life crisis mode and thus their lack of fertility is nothing to do with their mode of transport at al...whoops, excuse my political incorrectness...bad day!
