I watched your part of the video and I'm looking forward to your future projects. In your presentation you mentioned breathing exercises. Are there specific breathing exercises that would be a good adjunct to the HEGduino training? Is there a proper routine or sequence, like breath training first then HEG? I have been doing the training on random days for 3-10 minutes which is about how long I can go before I zone out. I'm not following any schedule or protocol. Is there an optimum timing between sessions? Is there an optimum length of session? Is doing this two or three times a day good? In other words, is more better? And I meant to ask this awhile ago. Where on the forehead is that flashing diode supposed to go? Thanks.
