I've survived for years in electrical and mechancal engineering environments without a scratch. Actually not true - chopped part of my finger off once!
Anyway, if you can do something safely, why not? A minute spent preparing could save pain, suffering and an unnecessary encounter with David Manning in a professional capacity. Imagine geting the "kiss of life" from dave - that's enough to scare you into safe working practises
As for unplugging the telly - what a silly idea! You might give yourself a back injury bending down...
