Personal Hygiene is very important. If you do not take care of yourself the bacteria & stinche building up will become sickening to you and others.
Because when you be a good friends, God bring you good friends
Because there's weed now instead. thats a joke but the real answer is that people now understand the dangers and life-long threats it presumes such as lung cancer
You have a lot of control over it. You can choose to be active, you choose what types of foods you eat. You can also control if you smoke, or drink. You basically have around 80%-90% of control. If you do the right things I think It will lessen your chances of having the disease.
Hope this helps!
