I'll beat my head against any wall until it breaks with a boss fight, as long as I can get back in the fight straight away. Otherwise it's just putting annoying simple shit I've already beaten in the way of my goal, and that bores me.
I'm in my fifties too, but look back on 25 year old me and see a fucking idiot. I know it's true because I'm a lot smarter now, but still a fucking idiot. I wouldn't mind a 25 year old spine, though.
