invincible - hardly
never be in danger - not in this world
armed - you betcha, but then I have been living by PowderMonkey's checklist for a very long time. If my weapon ever has to come to bear on a target, SHTF/WROL has come upon us and I will survive.
I’m armed as well. However I’m well aware that better men than me have died with guns in their hands. Only a fool of the greatest magnitude believes he can’t lose in a firefight.
