I'm the world's worst liar, and I'm 22 years old. You can read my facial expressions like a book, so I had a lot of fear in that moment that my whole house of cards was going to come tumbling down in front of me. I wasn't having a particularly strong sales moment, so I cracked up for a second and continued teaching without answering. Of course, that invested every other student in the class in the answer to this question.
"42!" (I don't think that one was serious.) "34!" "25!"
"Nah, he's at least 30, yo."
Clearly I wasn't getting out of this without an answer. My internal random number generator landed on 27. "27 - now Marcus, remind me how to test if a relation on a graph is a function," I said.
They totally bought it. The grumblings I heard afterward were that I was lying and lowballing my age.
1) Continue wearing a tie. Backwards hats cut your age by 15%, and ties apparently inflate it by 30%.
2) Kids are pretty gullible. I'm on the lookout for strategies to positively exploit this more.
