STAFF at a Lake District health and beauty spa are experiencing a 'twins' sensation.

The Geminian phenomenon is happening at Oxley's in Ambleside, where spa manager, Sally-Anne Maher announced that she is expecting twins in the summer, despite having no history of multiple births in the family.

In addition, holistic therapist Rachel Hunter, 33, spa therapist, Jessica McKenzie, 23, and hair apprentice Megan Broomhead, 19, are all twins.

In 1980, only one in 50 children born was a twin, but now that figure stands at one in every 35. With every year that passes, the number of twins born increases by 10 per cent.

The twin correlation at Oxley’s is yet to be explained, but Sally-Anne has reported ‘feeling great’ and expecting identical girls, has been 'twin-undated' with good wishes from Oxley’s customers.

“We are at a loss to explain the presence of so many twins working at Oxley’s. There must be something in the water,” she said.

Sally-Anne is due to give birth at the beginning of July, just in time for ‘World Twin Day’ which is celebrated each year on July 3 and will no doubt be enjoying a number of Oxley’s Decléor mother-to-be treatments, ahead of the big day.
