Past actually troubles alot if you don't cope up to solve the issues.
I guess what ever we take as an over dose or something extremely high causes a trouble when we just go deep down inside in we actually forget the way out, no matter what if do could be, that's cause the extreme amount of trouble. No matter how much precautions we take there's still some of it within us, so every thing we do should be balanced and equivalent in terms of intake that's maintains the trouble to get less or even sometimes don't arise or if it does we have the inner potential to manage it.
