Interesting, but certainly correlation is no indication of causation. After spending 10 years in Cambodia, one thing I don't trust are any statistics from that country. Even NGOs have a hard time collecting information in Cambodia due to government interference. Most of the country lives in the rice fields too, and those people are never included in any statistics.
We are so consumed by trying to survive day-to-day though, there is little time here to think of things beyond our front door. !ENGAGE 5
