deep down

From my Tickle.com Ultimate Personality Test:

If there is a change in the air, Thinker, nobody is more aware of it than you. You have an unusually refined sensitivity to subtle changes in your environment and from time to time, this can manifest as a fear that the worst is going to happen. You may have a tendency to be constantly on guard because you ultimately are working to prevent a perceived catastrophe from happening.

More than three million Myers-Briggs Type Indicator tests are administered each year in the U.S.: more than four million people have taken Tickle's Ultimate Personality Test.
