I just try to navigate the internet with as little "logging in" as possible. Youtube always had an age restriction that forced you to confirm your age by logging in but it could be bypassed when watching the video embedded on another site. I just tried for the Hitman 3 trailer on /r/games and it didn't let me. That's the first time this happened. Could it be just some adblock thingy? Or are they no longer letting you watch restricted content without logging in?

What are your favorite youtube channels to watch when you're in the mood for something positive and uplifting? No genre restrictions or anything, just something that really oozes the joy and passion that the creator has.

I'll throw this one out there to start: Bicycle Touring Pro. He makes wonderful, slow paced and positive documentaries about his solo and group travels on his bike around the world. If you ever want to just zone out for a moment, throw this on and you just might be inspired.
