Where does the physical start and the mind end?

I often find myself categorizing the the physical is somehow more “real” then whatever else there is. This whatever else, my perception for instance, is in reality the only thing that I can say is “real” as it is the only thing that I can truly grasp.

So there is this glaring question. What is this only real thing that I can grasp if it is not somehow physical? Where does “reality” stop and physicality begin if these things are in fact different?

It is often said that the simplest explanation is usually the correct one. So if this is the case then doesn’t it seem reasonable to say that everything is one thing. So which one is it? Do we live in a purely physical world, where everything is in fact a function of physical interactions or alternatively are we in a world where everything is a function of perception where this idea of perception is all that there is without what we deem a “physical” world.

Whichever way it is I’m going to keep convincing myself that this coffee I’m drinking is delicious no matter what my senses keep telling me.
