'Culture' is everything we don't have to do.
Culture consists of the gratuitous stylistic extras that we add to the things we do have to do.
You have to eat, but you don't have to decorate elaborately prepared curries with silver leaf. You have to move around, but you don't have to dance.
Culture is a biological drive for humans. It is not something that we just add on at the end, after we've dealt with all those survival problems, but something we keep doing all the time.
