more questions that won't leave me alone

what is meant by shared experiences? if each person's life is unique, can we ever share an experience? will seeing a scary movie provide the same adrenaline rush to me as it will to him? what if we could eliminate all outside influences and variables and in a controlled experiment allow 2 individuals to go thru the same occurence; would that be a shared experience. or just a limited shared affair w/in the experience. why has this popped into my head? why do we not get along with each other if our time on this planet is so short. we don't we make the most of it while we're here. what am i meant to do with my life? going back to school to study history is a reoccuring theme these days. i crave some good ol' fashion book learnin'. sitting in class and letting the lecture drizzle over me like a refreshing spring rain.
