How does Chicken Pox kill children teens and adults?

yep

Yes. Since Chicken Pox is contagious, the primary way to get it is from being exposed to someone else who currently has it - whether that be a child or an adult.

Adults can catch chicken pox. But most times it can be very painful so its better if you catch it as a child because it wont be as painful.

Yes it is but the older you get the more dangerous it becomes having them so its important that you get into see your doctor as soon as possible.

No not really if the person has it then you can. I passes just like a cold!
