You don’t want to sit and live in fear, but breaking something when you’re in your 20’s and 30’s is way different than when you’re a kid. Work in an office and break your hand – there goes working fast on your computer. What about if you worked in a factory or were a waiter? A broken bone would really derail for life in a big way. So when it comes to keeping those bones intact – try to avoid these activities. Okay, maybe not avoid them, but definitely be more careful when you do them!
