The following is slightly tongue in cheek, but I don't normally place a stable boundary between program and data on myself, I revise it depending on purpose. The following is one view I find useful sometimes

Nope, I'm all program. What you would call data is just programming in weaker languages than Turing complete ones. I can rewrite my programming, do meta analysis on it.

The information streaming into my eyes is a program that I don't know what it will make me do, it could make me flinch or it change the conceptual way that I see the world. The visual system is just an interpreter for the programming optical signals.
