Lithium (again)

A while ago I got all excited about Lithium (and even mentioned it here). Though I invest for entertainment (rather than making a fortune), my lithium done good: So my wife sells her lithium stock and ... uh ... I sell mine, too. (Am I henpecked?) Now I'm sad and will probably buy back. It's for health reasons (adrenaline production, coronary stimulation, etc.)
