Helpful skills to have in emergency situations?

When I say helpful skills in emergencies I mean like I really hate to use this term but like a zombie apocalypse or a apocalypse in general and I mean any type like I dunno the rapture or a nuclear fallout or anything you get the point and helpful skills like first aid, hot wiring, siphoning gas, trap making, self made weapons and maybe even skills you could use for like prepping your house or car for danger or emergency and other skills like lock picking btw dont get all whiney and say you dont need that stuff or nothing like that is ever going to happen because in general I mean any type of emergency apocalypse or not I'm just really interested in this stuff also
