It isn't professional to include your high school experience.
You wouldn't put your high school extracurriculars on a curriculum vitae, as it is considered unprofessional. Why would you treat this any differently?
His delivery isn't the most eloquent, but the message is correct. OSUdoc's right, don't include high school activities.
Did you continue your EC activities in college? If so, then include them. If not, why didn't you? Maybe you could state in an essay that "my love of doing _________, fostered in high school, continued/increased during my years at _________ college/univ."
To rely on activities from high school would not be in the best interest of medical schools. They need a "current" picture of you, someone who will be representing their school if they accept you. People go through many transitions/changes in college, so rarely are you the same person you were in high school anyway...
Bad example: A star high school football player (captain, all conference, etc.) who really wants to make it into professional leagues would not do so on the merit of high school sports accomplishments, but on what he did in College. NFL football teams wouldn't care what he did in high school. But if he was successful in the college scene that would catch an NFL team's attention.
Replace football, football teams, and coaches with scholastics/involvement, medical schools, and admissions committees, and well I think you get the jizzt of it...
I hope that was somewhat relevant-
