Without debriefing, what's the point of the image stream. Image streaming is a information gathering process.
My protocol includes up to 4 image streams in quick succession to answer. Usually takes about 40 minutes and yes I always debrief. Since I record my Image Steams I debrief by writing. Debriefing is to collect their meaning, the message or information they hold. If I did my image streaming by writing I'd debrief by recording it.
Win found that we can Image Stream for an hour a day and that's his target for folks image streaming. He's not found that we need to image stream more than that, nor are people generally willing to Image Stream more than that.
If you were to image stream for 7 hours in a day, yes you would need to exercise. The real point is, doing image streaming 7 hours a day is anti-social.
