I checked on none because I din't find "All" option.
Single source is only truth when it comes to a mother womb who delivers a child. But learning process needed to be like a horse which delivers at footstep though it may be painful dirt or sweaty fruits. We have the choice which one to inhale like a duck.
Thus, my suggestion is that inhale everything as far as possible you can and just do a little fart if you din't like.
