I think it is beneficial for the brain to be connected to the contralateral side of the body because of the position and connection to the brain that our eyes have.

Also anaerobic respiration releases far less energy (ATP) than aerobic respiration. So it is best for muscle cells to respire aerobically as they need more energy.
