This really matters in the womb until 2 years. This is when you do brain damage. It will be in all those 3 billion unless they have had access to supplements until 2 years. You are talking bringing high IQ's down to average and average IQ's down to below average. Below average to disabled. This continues the cycle. There's little reason to improving schools and giving them computers until you fix this.
