Thoughts on thoughts

I have a little experiment for you.
I noticed how my "alone" thoughts are different from those when someone is in the same room and/or building as me.
Self-awareness in solitude is way different than (self-) awareness when other people are present, even if not physically in the same room. That, in itself, is interesting.
What is compelling is that my thoughts changed as my position in space changed.
Let me explain: I was washing vegetables at the kitchen sink, facing a window, with my back to the door.
I then turned to the island to chop them up. In so doing, the window was now in my back as I faced the door. Boom! My train of thought became very different.
Somehow, I don't think it was related to the task at hand but to the environment I now saw.

This goes hand in hand with my mom's theory that as we age (and become really, really old), we can't hold our heads up much and start looking at the ground. This in turn shrinks our world to where our feet are and turns our world into a tiny piece of land... This affects our mood, our interests, and so on.

I guess it also speaks of body language where if you walk confidently, you think positive thoughts and the like. Sort of like people meeting on a bridge and mistaking their elevated heartbeat for love... Hen or egg, egg or hen...
