Youtube for the win!

I love youtube. I have been watching a lot of youtube videos on a lot of stuff like iPhone, beauty and weight loss videos. I find watching videos before I go to bed makes me sleepy and relaxes me. I usually watch it on my iphone before it is dead! My iphone dies too quick when I watch youtube videos. I have to get my videos in before bed!!

Do you watch youtube? Which videos do you enjoy watching??
