Hello. With all the talk and speculation about growth stunting during puberty because of an "imperfect" lifestyle, which normally means imperfect nutrition or not enough sleep, which is often talked about here, I wondered something else. Can this imperfect lifestyle affect your adult voice? Quite often I notice that while my dad, now in his late fifties, has a quite deep and "strong" voice, while mine is, well, not a "girl's voice", but certainly quite higher and kind of less "masculine". So I wondered if this could have to do with the lifestyle you live during your growth phase? Can imperfect diet, imperfect sleep and imperfect exercise during puberty not only affect your final height but also your adult voice, or is this aspect rather purely dependent on genetics?
