    You can relax if remembering everything isn't your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.

Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers found that the neurobiology of forgetting can be just as important to our decision-making as what our minds choose to remember.

Making intelligent decisions doesn't mean you need to have all the information at hand.    It just means  you need to hold onto the most valuable information. And that means clearing up space in your    memory palace for the most up-to-date information on clients and situations. Our brains do this by    creating new neurons(神经元）in our  hippocampus, which have the power to overwrite(重写)existing memories that are influencing our decision-making.

If you want to increase the number of new neurons in our brain ’ s learning region，try exercising. Some aerobic exercise like jogging, power walking and swimming has been found to increase the number of neurons making important connections in our brains.

When we forget the names of certain clients or details about old jobs，the brain is making a choice that these details don't matter. Although too much forgetfulness can be a cause for concern，the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decision-making by stopping us from focusing too much on unimportant past details. Instead，the brain helps us remember the most important part of a conversation.

We can get blamed for being absent-minded when we forget past events in perfect detail. These findings show us that total recall(记忆）can be overvalued. Our brains are working smarter when they aim to remember the right stories, not every story.
