Excellent tips. Something I advised my recently widowed mother to do was get security for her electricity meter. This was reasonably inexpensive and involved a guy coming over and fitting a security lock and an unbreakable viewing window. The meter reader can see the meter clearly without opening the box and no-one can disconnect the electricity.
I always lock my car doors when going anywhere (I have had 2 experiences where people tried to open my car doors whilst I was stopped at traffic lights). When walking around the shops or to and from carparks I carry my car keys in my hand and spread out between my fingers (bit like brass knuckles) running is always the best option, but if you can't the keys are a handy weapon....and ladies don't ever be afraid to go for the eyes...it could save your life. I learned this from my step-father, who served in both the Military and regular police service.
