Lemons, Spit, and the Sensitive Soul

You may remember the post about introverts tending to be more upset by grammar and spelling errors than their more outgoing brethren (http://somanyinterestingthings.blogspot.com/2016/03/the-sensitive-grammarian.html). I bring it up because a similar underlying tendency is at work in this experiment. Lemons, your saliva, and a simple Q-tip will help you determine (if you don't know for sure already) whether you are, in fact, an introvert or an extrovert.
