The Big Plastic Count

That’s good. You can do your own analysis. See if some weeks you use more plastic than others. It’ll be interesting to know if you use more or less than you did last month or if it’s pretty much the same.

Wonders will never cease, I've found it. I suspect it'll be much the same , we're very much creatures of habit.
