I've never heard of it I've heard of it but don't understand it I understand it, but I don't see how it's useful I hate it because I heard a bad thing about it I see how it could be fun for some people, but not me I use it, but it's just a toy It's becoming more useful for me I use it all the time I could not imagine life without it Seriously, how did people live without it? I'm not addicted It needs to be regulated
