Being ambidextrous could give you a cognitive advantage —
In a review of scientific research on the subject of handedness and
intelligence, researchers found that neither lefties nor righties came

massive supply of irrigation water that's typically used by vegetable
and fruit farms. The downside: Way less yield.

alternative, and may have a couple new fuels that could do the same job
with less risk.
