I think culture is something we all do everyday whether its the clothes we chose to wear, to the music we like, to the food we eat, culture is expressed through everything everyday.
I also believe different cultures can be inhabited around the world as people travel and exchange the many cultures there are. Everyone has their own personal culture but this is contributed by your parents and family as they might of been exposed to a mixture of cultures whilst growing up themselves. This all has an impact on your own sense of culture.
