Lipton's Sandwich Analogy

In Chapter 3, Lipton explains his ideas the membrane, the “magical membrane” as he calls it, and how it controls the life of cells. He described membranes as being an intelligible life, comparing it to a sandwich made up of bread, a large hunk of butter, and both seedless and seeded olives, something you don’t find on the Subway menu. He shares about the proteins of the membranes, how they connect to the “mem-brain”, how the membranes react to their environment, and how people receiving diseases has less to do with our cells and more to do with how we run our lives.
Out of the analogies he used, one that I found most interesting (mainly due to him comparing it to food) was his sandwich analogy. He compared the structure of a membrane to that
of a bread, butter, and olive sandwich, topped with dye. The dye seeps through the bread, but stops at the butter, due to butter being an oil substance, stopping the dye. The dye instead seeps into the olives, reaching the other end of the sandwich. The sandwich was representing the wall of the membrane, while the dye that seeped through represented nutrients for it. The wall of the membrane is almost like a food filter.
Something that Lipton didn’t fully convince me on was the last couple of paragraphs, primarily the last one. He states that some diseases, like ones having to do with cardio and stress, having nothing to do with cells but have more to do with our lifestyle. I agree with this. But he then states that diseases have to do with lifestyle, and nothing to do with cells, which I don’t fully find true because I believe that there are probably diseases that do affect and deteriorate our cells, or maybe even diseases that are actually caused by a malfunction of cells.
