Background.... I am a firearms safety and shooting instructor. In teaching skill for that..... I always taught 'weak hand' shooting. Shooting using your non-dominant hand.

Carrying that over to emergency prep.... I challenge you. go about your normal routines with one difference. Change hands.

Brush your teeth with your other hand.

Pour your drink with the other hand...and drink it that way too.

Shave with your opposite hand.

Clean yourself with the opposite hand (think toilet).

Try writing.

You will soon realize a simple task has become so much harder. You will come to appreciate how second nature some things have become and will come away with some very good skills.
