Some memories are better off forgotten. Like your ex-boyfriend's phone number or the reason why you dated your ex-boyfriend in the first place. If forgetting can be a blessing, why do we more often think of it as a curse?
Many of us have the tendency to focus on what's absent in our lives rather than what's present, and memory is no exception. We notice the time our spouse/child/roommate forgot to take out the trash rather than the countless times they remembered to do the dishes. We agonize over the bills we forgot to pay rather than praising ourselves for the errands we did remember to run. I know many people who wish their memories were better, but I've yet to meet someone who wishes his memory was worse.
The latest edition of Wired magazine features ways to increase your brainpower, including improving your memory. One article highlights Piotr Wozniak, a man so obsessed with perfecting his memory that he has created a computer program called SuperMemo that calculates the ideal time to practice remembering every piece of information he wants to learn. His life is extremely regimented, with the computer dictating exactly when and what he studies. As you might imagine, all of this comes at a cost to his social life. Although he's married, it's unlikely you'd see him out at a party.
