how do i stop my mac from shutting down when pressing the power button?

[john]

whenever i'm on the internet or facebook or something my brother always comes by and hits the power button then enter really quickly and my mac shuts down automatically. how do i stop my it from being shut down so easily?
also sometimes he does this thing where he presses option-command-eject (or something like that) and it freezes my computer for like 10 minutes and then shuts down. can this be stopped also?

You can't easily stop that. Maybe you need to solve the true issue, I recommend punching your brother when he does it.

change the settings. or maybe clean your computer, remove unwanted things.

No, I'd say this is more of a social problem than a technical.

Don't let him go near it. If he does punch him in the face or something
