It’s surprising but also sad to see how things have changed for children, both in rural and urban areas. Years ago, kids moved naturally because life demanded it as there wasn't much of a moment transportation system especially here in Africa. I remembered that I had to trek a few kilometres every day to school. But now screens, long distances, and processed food have taken over even here in Africa. Now most of the natural physical ability has been replaced by the gym.
As you said, parents and society play a huge role in this problem, yet many don’t realise how much damage unhealthy habits cause over time. We worry about protecting children from physical harm, but we overlook the silent harm caused by inactivity and poor diet. As you said, it all starts in childhood. Helping kids stay active and healthy is one of the best gifts we can give them for the future. But parents these days often say I can't allow my children to go through the difficulties I went through when I was a child. They have turned the moment they had to trek miles to school into a sufficiency on the part of the child. Also, they have glorified fast food as a natural and freshly prepared meal.
Engineered fitness. It is better than nothing, but most people aren't going to be able to stay consistent at it. It is "extra" to do, and many are looking for less to do.
Exactly. It is also interesting when people who are in poor shape, protect themselves from getting hurt - what have they got to lose? :D
