Auntie Flo, on the rag, girl flu, back in the saddle, jam and bread, going to Oklahoma, howlin’ at the moon – these are just some of the many English expressions used to avoid the embarrassing subject of menstruation. Period is still portrayed as a taboo, around the world. Different cultures view menstruation differently around the world. Some celebrate it and the others hide it or rather, shame it. Women have more periods now than in the past, because until the advent of contraception and bottle-feeding, women were either pregnant or breastfeeding for much of their lives. Also, poor diet and hard work meant that until the 20th century, most girls did not reach the menarche – the first period – until 17 or 18 years. The average age of menarche has dropped over the past century to 12.5 years.
