Person I know who takes no precautions whatsoever seems to have terrible luck with ram failing. Yet mine which I get the cheapest stuff they sell generally seems rock solid.
Not sure if there is any connection at all, but ram would be one of the easiest to damage with all those data lines sitting unprotected at all on the gold edge connectors etc.
Different people actually generate different amounts of static, it depends how much they sweat, what clothes they wear, humidity, etc etc etc etc.
If you are working on a PC, leave it plugged in with the mains switch on the WALL TURNED OFF. <- Read carefully, turn the switch OFF
You can then touch the chassis to discharge yourself and hold it while you handle the RAM, easier still is to clip your wrist strap to the chassis
I have an antistatic mat that I lean my elbows onto. Same diff.
