7- Air Pollution
Pollution prevents a pure supply of oxygen to the brain for healthy cognitive function. It is advisable in this day and age to wear a pollution mask while travelling.
8- Working Your Brain when ill
This is a pretty dangerous thing to do because being sick is your body’s way of telling you “please rest” that’s because your immune system is on overtime trying to fight out the infection, you working won’t do that any good. It damages your health and impedes your brain which has to work extra hard.
