A river is a large body of water that flows over land in a long channel. Most rivers begin high in the mountains or hills. A river's source may be a melting snowfield or glacier (although in Namibia we generally rule these 2 options out!), a spring, or an overflowing lake. As a river flows in its channel, it receives more water from streams and other rivers, and from rainfall. At the end of a river is its mouth, where the water empties into a larger river, a lake, or an ocean.
Canned soft drinks, from Diet Coke to sparkling apple juice, are available ice cold from just about anywhere – which is fortunate, considering the amount that you'll need to drink in this climate. They cost about N$2 each, and can be kept cold in insulating polystyrene boxes made to hold six cans.
The Namibian education system has been evolving since the nation achieved independence, although the dream of equal education for all remains tantalizingly unreached. A program of pre-primary education is unrolling, and is hoped to be completed by 2013. Pupils spend their first 7 years at primary school from age 6, where they are promoted from grade to grade on the basis of competencies.
