Yes, cultures can affect the way people live their lives. Here in Africa we usually attach cultural and traditional practices to seasons so we could get the best moments out of it. You talked about people being too cultured, here we don't usually keep to time, we get started mostly we get the right amount of people to do the work. Different cultures, different beliefs I guess so.
Not keeping to time is fin in environments where it isn't necessary, but in some places/occupations, it is required. It makes it a challenge for everyone involved in those cases!
