Some people are daredevils, and laugh in the face of danger.

As a result, they'll willingly partake in dangerous activities like bungee jumping and skydiving, or will go scuba diving with sharks without a second thought.

Others though, proceed through life with extreme caution, and wouldn't be caught dead partaking in any of the above.

However, these same people might not realize that they might have once put themselves in extreme danger without even realizing it.

As some things which appear to be completely harmless and risk free, might actually be far more dangerous than they might seem.
