Mark Harmon – 72 Years Old
Mark Hammon’s success doesn’t surprise us. He has a charming on-screen presence. But what’s more impressive is his academic and athletic achievements. He excelled in college football at UCLA and received the National Football Foundation’s All-round Excellence Award. He also graduated with honors in Latin, showing his intellectual prowess.
Before becoming an actor, Mark considered a career in law or advertising. You might recognize him as Special Agent Jethro Gibbs from the TV show NCIS or as Secret Service Agent Simon Donovan from The West Wing. Mark still plays Agent Gibbs today.
