Stress drills are different depending on one's occupation and age.
At 73, My stress is relieved by the comforting feeling of the SIG P226 under my arm when out, or the fairly sophisticated alarm system at home, backed up by my Benelli M-4 beside my bed.
My daughter's bedroon door is solid and dead bolted as wel. Her revolver is in her nightstand and she is quite skilled in it's use. That too is a great stress reliever!
