Some years ago I proposed a classification of the human races, based solely on physical characters.
These units are "theoretic types" formed of an aggregation of physical characters combined in a certain way.
The explanation of the pernicious consequences to the psycho-physical characters of the children of parents too young or too advanced in age does not present much difficulty.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "physical characters" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
