Glad that someone asked; it's from the book by Dr. Stuart Farrimond. These are random topics I pick to post. For the graphics, I would say these are from the books too, but taken from different websites and sources with credible information and stats, so you know they give acknowledgment of these graphics. I don't write this on my own because he has already dumbed it down enough to the point that I don't think it would make sense to write. The good thing is that everything is up to date information.

In my first post in ~Healthandfitness territory, I acknowledged him, see #850069
