Research has shown that STDs are considered by grown ups to be a ‘young’ problem. This blissful ignorance has led to a dramatic rise in the number of 30-40s being diagnosed with the sticky little issues you found out about at University and hopefully left there.
Because more and more people in that age bracket have lowered their standards, updated their dating profiles and gone on the pill, infections like Chlamydia, usually more prevalent in teens and twenty somethings are finding their way out of the playground and into the queue at Waitrose.
That is in no way as disturbing as the 400% rise in Syphilis diagnosis in people over 75 though. There’s a mental image to have with your coffee.
