It's easy to forget that for every flashy, handpainted wall advertisement you see in a city, there are a handful of people who endure discomfort (and risk death) to put it there.
Online tabloid Vocativ made this mini-documentary about these painters, who call themselves "wall dogs," and it's a refreshingly straightforward and unglamorized piece of work. The painters mostly talk about how they prepare for a job where they spend most of the day hanging from a chain, at the mercy of the elements and unable to step back and get better perspective of their work until it's complete.
But there's no bitterness or false bravado in any of them. In fact, they all seem pretty happy with what they do, which isn't something a lot of us can say about our jobs. Watch this as an antidote to the other cynical garbage you read online in a given day.
