Game of life, PowerPoint, and a bunch of non-PL stuff are all Turing-complete. I don't mix up terms, I did use a slightly sloppy terminology but it is the correct concept - and my point is that we don't know of a computational model that can't be expressed by a Turing-machine, humans are a physical "machine", ergo we must also fall into that category.
Give my comment another read, but it was quite understandable from context. (Also, you may want to give a read to the Turing paper because being executable by a person as well was an important concept within)
