Your prediction about a future trend
I think everything will be changed and I call it progress and that is very normal I mean you should have this prediction to watch lots of strange things like strange trends maybe trend about some kind of foods or even water. Like tattoo because at past nobody believed that tattoo is going to be one of the popular but now as you can see in every lots of people use this kind of thing on their body. I just hope in future we do not see any dangerous trend which hurt people.
