crickets can be (and are ignored)

You haven't heard the ring tone on my cellphone.

A Culture is not an abstraction, a Culture is as concrete as DNA.

Then why don't we use the terms DNA and culture interchangably?

An abstraction is exactly what 'culture' is. I consider it more of a distraction, but... I'll refrain for the moment. There are so many cultures based upon so many different amounts of different defining attributes... it can't get any more abstract... Yet, this is how I understand it, and as *we all know, a culture of one is as valuable as a culture of a million.
