When I first stared working on computers I had one, but I quit using it and never had a problem.
When working on a computer, do you bother with the anti-shock wristbands or do you just touch the Power supply alot?
If we take a ram module. You might not "fry" the module by touching it. But you can certainly damage it, and in time it might give you blue screens because some cells in it can no longer hold data
some time ago, i read an article where they examined such a module in an electron microscope where they could see the holes the static electricity had made
