I can't speak to all teens, but I have seen a vast improvement in my two since going back to school. And yes, we are incredibly lucky to be in a school that can really make it work and I completely understand that not all schools can do what they've been able to do. Having sports and school was a complete blessing for my two teenagers. There are still things they can't do, but what they can is a blessing.
My youngest faired a bit better overall, but our area was able to open things up for younger kids faster than older kids because transmission rates are so low in kids under 15 here. His life has been more normal (masked, but normal) for longer.
