The longest I had spent in the CB3000 was 28 days.
Last night may wife asked me to bring her up some warm milk to help her sleep. When I handed it to her, she complained I had made it too hot. After accepting my apologies, I quipped "oh we'll, that's another day added on" to which she replied, "no, month" then she thought for a bit and said "make that six".
She was joking...... At least, I think she was joking!
