First one: It's to believe that when someone knows you when they're talking behind your back (usually about bad behaviors), you will get sneezing all of the sudden no matter where you are or what you are doing. It's a very common myth around Asia countries, China, Japan etc.Also it's a common scene you'll see in TV show, dramas.

Second: After watching the episode of the hammer bridge drop and driving in a truck through a harbor bridge. I got a hitch, what if a guy falling with a giant object in a high level above the water, eg. a guy falling on top of a truck, can he save himself by jumping before the truck hits the water surface? I wonder if the force of the jumping can actually break some of the G-force enough to save a falling person.

Love to see these myths to be tested on the show. Cheers.
