I surf a lot and think nothing of swallowing sea water. However, a new study by scientists at the University of Exeter highlights how badly sea water is polluted - which makes me think twice.
By taking rectal samples from members of Surfers Against Sewage, the researchers hope to find out how sea pollution - including antibiotic-resistant 'superbugs' - affects our gut bacteria.
Now the sun is here I'm desperate to get out on the water. I'll be careful not to swallow too much water, though.
