Whatever age you are, you can make yourself more ready to defend this country and to fight our enemies. If for some reason you cannot train yourself in martial arts or in shooting, for example, you can take the online FEMA emergency preparedness course or find some way to support your local police, Search and Rescue, or whatever. Think about ROTC if you're a student. Think about supporting the troops.
There may not be much we can do to prevent or deal with a terrorist attack, but nearly all of us could do something more that we are doing. And I assure you, the most stressful thing is to sit and feel like there's nothing you can do.
