I love people who are very honest and very open and don't pretend to be anything they're not.
I also assume that they are not simply the physical properties of things as now conceived by physical science. Instead, they are ecological, in the sense that they are properties of the environment relative to an animal.
The tricky thing becomes: Do you know yourself well enough to then portray that on screen? And for me, I find that really hard. I'd rather hide behind accents and funny walks.
