A Life Of Drugs

Someone had something interesting to point out to me the other day:
“Dopamine is a chemical the brain produces to give you a feeling that you refer to as happiness. And as your happiness increses, so does the amount of dopamine secreted in your brain. And all the happy moments in your life are retained in memory only because the brain keeps a record of that excess dopamine. That dopamine is also the reason you behave the way you do when you're "happy"... do things that you’d not normally do. And as the dopamine content in your brain stabilizes, you become your normal self. But the brain does not like the normal self anymore, and craves more dopamine. And that craving makes you sulk, become morose, and unhappy. Man is, by nature, a happiness junkie.”

I’ve no reason to doubt this analysis, considering they stem from a Microbiology background.
But it gives rise to some thoughts; disturbing ones at that:
Happiness is a drug-induced haze. Nothing more than a trip from some cerebral suppressant/stimulant. And like all drugs, it’s overrated, addictive, and destructive. Mind-numbing at best, useless, at worst.
