Our brains have receptor sites for morphine, nicotine, caffeine and marijuana. That is because these substances perform functions which our brains do naturally. Marijuana, for instance, helps us forget – and it appears that those receptor sites serve in our memory functions.
A good brain knows how to forget. A healthy, happy brain forgets pain and suffering much more quickly and thoroughly than it forgets happy memories. The only downside I can imagine for this blessing is when it happens to memories of ex-lovers. For when we get into a fight with our present mate, our minds can go back and remember only the good things in the last relationship. Not only that, but if your former relationship was a decade or more ago, you probably also remember this over-idealized ex-lover as much younger and better looking than they would be today. So, us optimistic, happy-minded folks need to be cautious of these cognitive illusions in times of relationship strife. For the ex-lovers of our imaginations are probably not as beautiful nor as perfect as your mind is trying to trick you into believing. Ah the pitfalls of human reasoning!
