Primitive Technology Indo Edition: Two bros spend weeks hand digging a swimming pool around their underground house. As a mosquito I approve of this stagnant water design!

Amazing, but they should have built up their underground house so the inner wall was a good foot higher than the outer wall. You really want the best path for water to be away from your underground home not into it. For the amazing amount of work and ingenuity. Too bad the pool water can’t be easily changed and will probably attract every snake in the region.
