Yeh, had an ent chap telling me the benefits of a saline washout recently.
I must say, probably get any more washed out than on me surf board at Watergate Bay , but whenever I surf, and tumble, I seem to get terribly clogged, the only relief I get is by lying on a desk, head dangling down, whilst I thump the side of me head with the palm of me hand.
Probably not based in science, but it's great to see the trickle of ocean fall onto the carpet!
The swimming thing only works if I don't put me head under.
