Mercury conjunct Mars

Mercury supplies the words and Mars supplies the force, so speech becomes a weapon and a tool at once. These people think fast, argue well, and say the decisive thing before anybody else has finished framing it. Debate, engineering, surgery and journalism suit them. The cost is that the sharp remark leaves the mouth fully formed, and apologies follow it around for years. Mental restlessness is constant and hard to switch off. Headaches and a short fuse in traffic are the ordinary daily expression of an aspect that is genuinely useful when there is something to fight for.
