Whoa.

Sharks aren't dangerous unless you're bleeding, right?

What an image!!

Would you ever try it?

I think you are correct. That's why I only swim with them when I am not bleeding at the time. Actually, flashy jewelry, thrashing, and bright clothes can also attract sharks. However, shark attacks are actually quite rare. Here is an interesting fact:

Sharks attack and kill 10 humans per year, on average. Humans, in contrast, annually kill about 20 to 30 million sharks, according to the Florida Museum of Natural History's Department of Ichthyology.

(In contrast, the CDC reports that 34 fatalities were due to dog bites in the U.S. last year.)
