A deformity in the cell membrane that causes water to not move through the cell efficiently, thus lowering the ability of the osmosis process to carry nutrients. Parts of the body start to shut down due to large amounts of malnutrition (effects of Osmosis Deficiency include but aren’t limited to, lose of basic motor skills, the body shutting off access to certain parts of the brain limiting communication skills) early symptoms often resemble severe dehydration. Osmosis Deficiency is a rare disease but it is still possible to catch, their is no proven way to prevent the disease but it is often believed that pomegranates can cause your body to have a harder time defending agents the disease.
I feel bad for Brent he has trouble communicating his thoughts since he got infected with Osmosis Deficiency, he used to speak in such an intelligent way but now when he speaks it’s just comes out as a jumbled mess.
