Aubergine Man Fact 2: The thing that attracts them is usually the fish that ARE attracted to blood and can smell it for miles attracting to the blood, But sharks can smell blood, just not as well as some say, And they don't care for human blood, So if you scrape yourself in the water while surrounded in sharks, don't expect to be dead for a while, you probably will have time before they start to surround you, and even than they don't have That high of a chance of attacking you.
