But do you know about the ultimate personality test? You can’t do this one online; instead, you’ve got to do it in real life. Known as the lemon test, it requires a trip to the grocery store, but it’s totally worth it. 

Ladies and gentlemen, allow me to introduce you to the lemon juice personality test.

(I love puns, but will acknowledge that a line must be drawn somewhere.) Rather, the lemon personality test determines your personality traits, and whether or not you are an introvert or an extrovert, all by measuring your spit.  The science works like this. There’s a part of your brain called the Reticular Activating System, or RAS for short. It’s stimulated by social contact and by the introduction of food to our mouths.

In order to take the lemon personality test, follow the instructions below:

Extroverts produce 50 percent less saliva than introverts. Those numbers are hard to ignore.  It’s funny to me that the brain’s way of communicating that you are an individual who needs time alone to recharge and restore is by producing a ton of saliva, but there you go.

They would be forced to go to a party they didn’t want to go to, and when they were corned they could just spit out a massive amount of saliva and then flee.  That seems unlikely, but it’s fun to think about all the same.  I tried the lemon experiment myself and confirmed that I am one heck of an introvert, and my floor is still covered in the salvia to prove this. Even typing about it now my lips pucker and my mouth floods with saliva. I wonder if I’ll now react that way when presented with social obligations as well. We’ll have to wait and see.
