I would have to try it in succession and try not to get too tranced out with it on. I usually get lost in inner-space when I put it on and get into some fave music. Instead of sensory deprivation, it's like an audio / visual overload. You don't even feel your body after a while with images and thoughts taking over your whole existence. When the CD suddenly ends you take it off you're all floaty and in a euphoric mood which lasts quite a while. Perhaps I get this desirable effect because the instructions are to use the machine for 15 - 20 mins and I generally leave it on until a CD is over (50-70 mins)? lol!It would be interesting to see if using that brain stimulator thingy changes your score.
But in my defense, I didn't understand the instructions
Do the Japanese count a year in the womb as your first year?
