that isn't true again....
When in resting, you will breath differently then while sitting.
And when you deep sleep, its something entirely else... you can tell a person is sleeping from the way they breathe on top.
Its not fundementally the same.
Hey i am mearly stating what multipul doctors have told me.
Don't hate the messenger, they all tell me definitely do not setup a anything larger then possibly a small beta tank... less then 2.5g in your bed room, unless you live in a location where your windows are always open non stop, and humidity isn't a factor, because its always vented outside.
If you doubt my statement, go ask your primary next time you do your annual.
