The Heart and Brain
To put it in perspective, imagine you're eating fast food for just a month. Only fast food. You feel good when you're eating it, right? Though if you were to remain on that diet, it would put so much fat in your bloodstream, it could clog it up, resulting in either persistent chest pain or even a heart attack. Not a pleasant feeling. Those are the beginning signs of heart disease.
Another way of forming heart disease is laziness. Running in the morning? Nah, you'd rather watch Netflix. Staying lazy will have it's consequences. Apart from other disorders or diseases, it has many impacts on the heart. It's the same concept as if eating a lot of fast food. The lack of physical activity doesn't let fats and calories be burned. This adds up in the bloodstream, either clogging the arteries, a vessel, or a vein. This also can cause heart attack or a stroke.
In other words, it's best to refrain from anything that can result in a large buildup of fat.
Any damage to the brain could be life changing, since it controls everything we do. A blow to the back of the head could affect vision greatly. It's not enjoyable either. If a tumor were to form in the brain, vital parts could be damaged or even destroyed. Trouble speaking, hearing, and seeing are among the many outcomes if that were to happen.
On the list of many things that could go horribly wrong, we have dementia. No one is quite sure what causes it, but many theories suggest it could be hereditary. Dementia is the gradual decline of mental ability. There are many types of dementia but there is one that is very common. Alzheimer disease (AD) can happen with anyone, and it affects about 5 million adults. It is spotted most in women, but scientists are unsure if gender has to do anything with AD.
