A skill set on its own that we as adults have not practiced since we were in school. E.g problem solving for a 6 year old is learning how to swing a bat and hit a ball. What would problem solving for a 25 year old look like? Most exercises we do nowadays are easy to mentally figure out and complete, we observe it being done and then do it ourselves - leaving only the physical side of it as the challenge. Isn’t health= body, ‘mind’ and soul? When was the last time you were shown an exercise to do that you couldn’t mentally figure out?
