I calculate that I stay aware, in the best of days, a 5% of my waking time.
Most of it while I walk the dogs, or while I wait for something. The rest of the time I have seconds, or even fractions of seconds of awareness in which I'm conscious of what's happening, amidst a continuous state of just experiencing life the normal way.
I wonder how are things for you folks, how much aware are you on average. Let's throw in some figures, shall we?
