If you really wanna break a bone... Well its actually pretty easy, just be a fall guy.... With out the safety harnesses.... I mean i recall my friend breaking his arm by smacking it into the corner of a brick wall.... But that left quite a deep cut... You could always do what i did and get into a fight....and get your nose broken ...maybe if you that adventurous you. Could utilise the hinges on objects. Usually a good half of an hour of slamming the shit out of your fingers would work... Dont ask how many pieces your in though. I also from memory recall someone being run over by a friends bike... Maybe you should get a HEAVYWEIGHT friend and a bike. Use the floor. Show your arm and snap.... Enough said Other than its stupid to break bones on purpose, although i smell a troll, it can interfere with nerves and theres always a slight deformity to the bone afterwards
Either way. Its gonna be hard to break a bone. I find it extremely hard. Although i probably do self inflicted damage nearly every other day and only managed bloodshed...js
Fall off a horse over a jump then get dragged through the jump and slammed into the fence. You'll break a few ribs.
