A condition by which the body shakes. Often the result of the body's withdrawal reaction to foreign substances such as caffeine or nicotine.

The shakes can also be brought on by stressful situations, which may or may not include shock (usually the mental kind). Situations in which you might get the shakes include:

• after doing CPR on someone.
• having a brush with death, like almost getting creamed in a car accident.
• finding out that someone you care deeply for has been hurt seriously enough to require hospital attention.
• actually seeing that person for the first time after they've been hurt, especially if they are unconcious.
• if your actions prevented someone else, whether you know them or not, from becoming any of the variations of dead, so instead they had a brush with death.
• any kind of confrontation with a bad person, whether its a mugger or a terrorist, regardless of what happens.
• I would guess that after you've killed someone, unless you're a psychopath or sociopath, regardless of situation.
• seeing someone die.
• seeing crimes against humanity.
