yes it is i feel really bad for you :(
Holding with breath and 'sucking' your stomach in flattens the stomach area. The extra skin, covering the rounded stomach, has nowhere to go. Thus the wrinkles.
Slightly less than 1% of the air that you breathe in.
It will push out, if you are breathing from the diaphragm.
no. as usually if not caused by gum disease, bad breath is caused by a gas from the stomach. someone who is lactose intolerant would have bad breath if consuming dairy produce as it would cause a stomach upset
no

slightly above 'see your breath' cold.
No. You breathe nitrogen with every breath you take. It is 78% of Earth's atmosphere.
I have pain in the upper area of my stomach whe i breath an dI cant stand up straight
Just take a big, deep breath in.
These muscles can sometimes be strained and can lead to chest pain in that area.
Because what you breath in is air (which is 80% nitrogen) not oxygen and what you breath out is air with a slightly changed proportion of gases as compared that which you breathed in.
