I'm going to respectfully disagree.  The problem is not the static or 
the ground, the problem is when you have a differential voltage between 
items.

If you always maintain a forearm on the frame of your device and handle 
things carefully while maintaining contact with the frame, you will all 
be at the same electrical potential.  Be sure to be in contact with the 
frame when opening anti-static bags, too. Hold boards by the edges, 
don't finger the gold contacts, and don't touch components if you don't 
have to.

This technique has worked for me for years.  I don't do sensitive work 
often, but I never seem to have all the 'anti-static' stuff when I need it.

The only danger is if you get carried away and lift that arm.
