I always remember when I first started surfing at the age of 10 in the North Sea. I was always sick and off from school with stomach bugs.

My anecdote is hardly scientific proof but this article certainly supports my thinking that I've now got a stronger stomach than most due to surfing at such a young age in terrible water conditions.

Over a period of a few years it just stopped and I was never ill again (after a surf)...apart from the dreaded and incredibly painful ear infections.
