The video which made me come here and write this post was this video I just watched of a person getting Henna off their right hand, and they were clearly filming it with the other hand.
EDIT: Thank you for those who said that this is an unpopular opinion. My first post here seems unpopular, which is good lol. And no, that isn't me being sarcastic.
Given that vampires are immortal and therefore have unlimited amount of time, they will end up being experts at every field because they probably run into problems that they have to learn stuff in order to solve.
