Take their bikes away from them, their dangerous

Also take their shoes away from them, too dangerous to be outside
walking.

Do not allow them outside of their room, too many things to bump into.

Do not let them outside, WAY too dangerous, what with insects that
bite, poison ivy, etc.

Round off all sharp corners in the home, including furniture, walls,
etc, then pad everything with a minimum of 3" of closed cell foam,
those hard walls and sharp corners are very dangerous.

Do not EVER take a child in a car, there is a chance of an accident.

Don't ever take a child in a boat, again, accidents happen.

You must home school your children, it's way too dangerous to allow
them on a school bus, and those school hallways are just way unsafe,
what with hard walls and floors, a fall could be a disaster.

A child should never, ever be allowed to play with another child, it's
just too risky.

The only downside that one may experience with this is their children
might be inclined to join the military to get some real life
experience instead of going to college.
