Hi. Hope evrything''s been going well for you.
Saw that you''ve recieved some tips in the shark issue. Please ignore the screen, misstaken identity etc. No screen will ever deterre any shark from doing anything, nor has there ever been any strong evidence that sharks has bitten humans as a result of misstaken identity. Two things will make a shark stay away though. Electric current and soap. Now, that''s not very practical, but if you don''t swim at night, late afternoons, when bleeding or close to inlets, you''ve got nothing to worry about. Sharks don''t eat people as we''re not fat enough (they would actually starve to death), and they don''t hunt for fun. Some sharks, like the Bull, is known for attacking humans, so if you see one, don''t go in the water. Tigers don''t attack often, and if you like to swim, the water''s probably to warm for a Great White.
No other speices have attacked humans without provocation to my knowledge.
If you''re attacked or approached by a shark, try very hard to stay calm. They are sensitive to heart rates and chemical reactions caused by stress.
Take care now, respect sharks, but don''t fear them, enjoy them.
Sorry about the spelling and the grammar, but I''m Swedish.
