1. 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. 
2. Overeating It causes hardening of the brain arteries, leading to a decrease in mental power. 
3. Smoking It causes multiple brain shrinkage and may lead to Alzheimer disease. 
4. High Sugar consumption Too much sugar will interrupt the absorption of proteins and nutrients causing malnutrition and may interfere with brain development.

6. Sleep Deprivation Sleep allows our brain to rest. Long term deprivation from sleep will accelerate the death of brain cells. 
7. Head covered while sleeping Sleeping with the head covered increases the concentration of carbon dioxide and decrease concentration of oxygen that may lead to brain damaging effects. 
8. 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. 
9. Lacking in stimulating thoughts Thinking is the best way to train our brain, lacking in brain stimulation thoughts may cause brain shrinkage.
