It behooves us to understand the power of gravity or its diminished or negative effect as we, Homo sapiens, evolve from going around from four limbs to bipedalism or working mostly erect or sitting on our buttocks. Evolution doesn’t favor a particular desire or anticipate the future; its particular end is to get that individual to live long and propagate more efficiently. Evolution cannot give you all the favorable advantages; only that selfish genes will make us the top predators. Unfortunately, the locations of the paranasal sinus ostia are not top in the list of favorable advantages. Hemorrhoids, chronic back pain, varicous veins, etc are other morbid consequences of bipedalism.
