Ive had a number of them. Couple of times out at sea. righting off a H2 series Kawasaki 750. Once getting arrested for suspicion of heroin trafficking in Malaysia. (not guilty).
But the time before last I lost vision in one eye while driving on a freeway in lots of traffic.
turned out to be something that went away in ten minutes ,that was easily explained by a cardiologist and happens to people with a slight prolapse of a heart valve when lifting very heavy things that they cant lift the day before.But the out at sea ones were the worse.
