Hmmm I believe it is colloquialism and social context !! if not I'll update my answer !!
You can use breaks in Microsoft Word, e.g, and also you can use blank when you want to start a new paragraph. But between two words, you can use only one blank.
risky behavior can be seen as different things, theres a difference then risky,brave, and just plain dxmb, risky is in-between brave and dxmb, risky means theres well, a risk to it.
risky things would include dr0nk driving, texting while driving, riding a bike without a helmet, people who do risky things tend to know what will happen if they do it but they don't care, they like the rush of adrenaline they get from it. some risky behavior is just flat out dxmb and others not so much.
hope this helps :)
