That is, to what extent can I observe what's happening in my body and the surrounding environment? And sustain that state of observation. At this point, the answer appears to be on the order of seconds. I doubt that I can go for even a minute without my thoughts veering off someplace other. What's really scary is that I can go about a mile, and realize that I've basically noticed nothing about my body or the environment. Yesterday, I walked right into a beam of wood that I didn't see.
This should be interesting if I can stick with the intention.
