@03a95182 That’s a big problem with almost every series that involves teenagers. That’s why they often use older people who are pretending to be teenagers. Look at the kids in Friday Night Lights; none of them were high school age when the series started, they were all in their early 20s. So  they don’t visibly age much over the years. 

 @71bdb419 Yeah, I watched too much 90210 back in the day not to recognize "teens" with male pattern baldness when I see it.
