A Little Electrical (House) Help Please....

With that said.....

My mom lives in a house built in 1966 and nothing is grounded (2 prong receps).

We have never lost any piece of electrical equipment or electronics due to lightning or surges in that house.

(and I've had tons of audio equipment and computers in that house) (and let me tell ya...lightning strikes and surges happen in FL on a monthly, if not weekly basis)

Are those things related?

IDK. Just making a statement of fact.
