naive?

haven't looked closely enough?

don't realize that we are all one, huge being called 'life'

and, no, there is no positive food and negative food.

each life we lead is a quest for survival that evenutaly ends

but the mega organism never dies

enjoy this life, live it to the fullest. don't try to be a vegetarian cow, if you are an omnivore human. accept yourself and love yourself.
