Interesting. Where do you divide the line between "macro" object and "micro" object? For me, I have much difficulty in seeing a logical consistency of being able to divide a line between one of the other i.e., they are both made of the same matter no? How do you logically create a demarcation between micro and macro objects? It is also true that our physical senses are very poor measuring devices incapable of seeing a great deal of phenomena that exists. This would include quantum effects. So, in my current view, the only demarcation that currently exists is our technological ability to detect quantum effects, and more recent experiments have demonstrated quantum effects on increasingly larger "objects". I am assuming of course, you are aware of some of the scientific research here.
