Yep. Back when gym class and recess time could involve actual exercise and competition, and there was some incentive to “be good” or excel at the sports activities.
Today, even when they DO have gym class or “recess”, they aren’t allowed to play certain games because of “injuries” from dodgeball, because of self esteem problems if a kid is picked last or close to last in choosing up sides...
Leave the kids alone and they themselves will sort out things on their own just as we did 50-60 years ago.....
