You can buy all of the special gloves, straps, ionizers, mats and geegaws you want for ESD protection, but common sense will always prevail. All the aforementioned items are for manufacturing environments where you hire uninformed people off the street to do the job.
The key is to keep you and everything you work on at the same potential. That's it. As an example, if you're installing a new memory card in your computer, you grab the card by it's bag (that brings you and the bag and the card to the same potential), remove the card from the bag and hold it in one hand (that keeps you and the card at the same potential) and grab the computer frame with the other hand and keep that wrist resting on the frame (that brings you, the card and the computer to the same potential) and then insert the card without fear of ESD. You, the card, the bag and the computer can all be sitting there at 2000 volts above ground, but if everything is at the same potential, there's no ESD.
