Happy smiling children. Growing up in nature makes kids strong and healthy. Thus a few kms walking on the daily path to school makes happy smiling children. Instead of playing computer, kids here play nature and have real fun. On my way down this jungle path along the mountain creek, I met a little girl, may be 8 yrs or so walking down to school with her father. That is normal and fun. Instead of fat little kids you have strong and healthy children. Again a measure of health care and disease prevention free of charge. Myself as a small kid, I had 3 kms walk to school through forest along a creek and I enjoyed it every day! Try to have your kids walk to school instead of driving them, or having them take a school bus. Live in a natural environment to offer healthy playground made by God.
