How can I prevent static shock when touching metal?

To prevent static shock when touching metal, you can try grounding yourself by touching a metal object with a larger surface area, like a doorknob, before touching the smaller metal object. This can help to equalize the electrical charge and reduce the likelihood of a static shock. Additionally, you can try wearing clothing made of natural fibers, using a humidifier in dry environments, or using an anti-static spray on surfaces to reduce static buildup.
