How can I keep WiFi from enabling itself on my MacBook Pro?

WiFi keeps turning itself on despite me turning it off. I get bad nerve inflammation from WiFi and I don't notice the WiFi is on until my hands begin hurting. Then, it's too late and it's triggered my erosive arthritis to flare up and damage my fingers.

I always have my MacBook Pro hard wired. But when I move from location to location I catch the WiFi being enabled, but not connected to a network.

What gives?

Bad enough this laptop wastes energy turning itself on with the slightest touch. Can't keep that disabled either.
