Change to CF bulbs because they save money and don't need to be changed as often. If you start to change your life "for the good of the world" without finding the reason it is good for you, you will spend your life feeling burdened by your decision to help out not heartened by your life improvements that give you benefits and also help our environment. Besides fluorescent bulbs contain Mercury.

As for shopping bags if you pick the right stores (try Whole Foods) they give you paper bags that count as ten cent coupons when you bring them back and reuse them. Good for you good for the environment.

Keep enjoying your shaves, best shave of your life and most comfortable too.
