A discussion of security measures covers more than which security product we buy.
It seemed to me that there was a danger of people drifting into saying things like "I am afraid I don't use any security measures on my computer, I am terribly trusting. " or "I always hide the front door key under the third plantpot on the left. It is quite invisible." or "I live next door to the Police Station in XXXXXXX so I leave my doors and windows open all day, even when I am out. No-one would burgle the house next to the cop shop"
Things you find stressful that other people don't notice.
