One question, when re-wiring an outlet, for instance to replace the old

If you are replacing your romex because it has no grounds, there are
2 ways to fix this without snaking new wires. You can put a GFI
outlet on the first outlet of the circuit, which then protects
anything downstream of the outlet, or you can protect the entire
circuit with a GFCI breaker. In most jurisdictions, code permits this.
You are protected against shocks.
