Is this definition considered universal Do physicians outside the US accept it I mean it strikes me as really weird because different ethnic groups have different average heights not to mention man are usually taller than women  how can the same standard apply to all While a Scandinavian man standing  may be perceived as considerably shorter than average the same height in other ethnic groups wouldnt be that unusual I come myself from an ethnic minority in which short height is a locally renown trademark cm so it would be interesting to know if this standard is universal ie intended to apply to all human beings or if instead a different height standard applies to each ethnic group based on their average height
