Stress shrinks your brain. Neuroscientist Lisa Genova explains how to strengthen it.

It may not feel like it when you can't find your phone or "lose" your sunglasses sitting atop your head, but your memory is an amazing ability -- and one we want to protect. So it's little wonder that any blips or blank spaces can send us spiraling into concern.

Some recall issues here and there are normal, says neuroscientist and author Lisa Genova, and not every lapse means looming problems. (And don't worry, forgetting names is a surprisingly tough thing for our brains to do!) But, Genova says, there's ways we can improve our memory, increase resilience and recall and be more comfortable with ourselves and our minds.

From making lists and getting Google's help to giving yourself a pop quiz, getting some meditation in, and just plain paying attention, these tips will have your steel trap gleaming.
