Brain Damaging Habits

One of my friend shared me following Brain Damagin habits. I am posting to help you all. Feel free to discuss and add some more.
No Breakfast
People who do not take breakfast are going to have a lower blood sugar level. This leads to an insufficient supply of nutrients to the brain causing brain degeneration.
Overeating
Overeating causes hardening of the brain arteries, leading to a decrease in mental power.
High Sugar consumption
Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.
Air Pollution
The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain, bringing about a decrease in brain efficiency.
Sleep Deprivation
Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells.
Head covered while sleeping
Sleeping with the head covered will increase the concentration of CO2 (carbon-di-oxide) and decrease the concentration of O2 (Oxygen) that may lead to the brain damaging effects.
Working your brain during illness
Working hard or studying with sickness may lead to a decrease in effectiveness of the brain as well as damage the brain.
