Uncles sat the cousins down when we were teenagers and taught us how to properly wield knives. There are knives throughout my house. And an alarm system.

All Veterans are trained in hand to hand combat rifle range and side arm target shooting....the best defense is not making oneself a target
...exhibit strong able posture and always scan your perimeter....remember your ten general orders....beware idiot's bragging of a home arsenal and gun shaming civilians

When you look for answers where there is no problem... You are the Problem.

My mom look. Don't laugh it's deadly according to my two sons....

A house with multiple doors.

I live on a peaceful island. I only lock the doors when I am away (sometimes). We don't lock our cars and often leave the keys in them (if someone steals one all we have to do is call the ferry and have the cars picked up). I have a sign that say "This property is gun free, NRA cowards not welcome and I get a lot of positive comments on it. Summers, especially weekends we are a little more cautious as that's when all the tourists come from the mainland. Our weekly police reports are often laughable.

A low grumble from Gaia (GSD) is usually enough 'though she be but small she is fierce'
otherwise, hands, feet, or whatever is around at the time ... not allowed an AR50 in UK, but every house is full of defensive weaponry. I have a hand axe beside the door - for chopping wood - but it is very sharp and on standby

Body odor

It's spelled self-defense.

Vigilance while out of the house. At home, locked doors.

A toilet brush at home. Sharp knives in the kitchen.

I never hike alone.
Don't walk or run at night.
Keep car doors locked. This saved my life at age 21.
Never look into my purse or at my phone while walking outside.
Keep doors locked at home.
Never wear high heels. I need to run!

A baseball bat, hammer, fist or what ever is close at hand .
You don't have to walk around like a 21st Century Demented Cowboy to defend yourself . Plus you look like a loser Pussy toting an unnecessary gun around .
