After repeatedly viewing your video to confirm the statistical accuracy of it's retention graph, I've come to the following conclusions...(and I didn't even have the volume turned up)
1. It's a Good video, it's engaging, it has a little surprise, you experimented with pushing the edge, sparked conversation and elicited positive and negative emotional reactions
2. There is a disturbing undercurrent in this thread that I want to address. You have a pretty face and a nice body. On you tube and in the world some people see this as threatening and an unfair advantage. This is evident from the catty little comments they leave. Accept this fact and strive to never compete on a level playing field. Always give yourself every advantage you can. This is a competition where we compete for subscribers and to bubble to the top of the search engines.
3. Youtube and the world in general is unfair. Just like in the world most of the written and social rules of Youtube were laid in place after the success of the big Youtubers. They were not put in place to help you succeed but, to hold you back. You broke the social rule of not showing a little skin to gain advantage. Well Anna, I say F***k the rules.
3.You should use all of your god given assets to achieve your goals. This is why I strategically place short clips of me lounging in my tighty whiteys and sipping a Bud in my videos.
