Since May is older Americans month, we thought we'd cap off the celebration by asking award-winning author and journalist Anna Quindlen about the moment she knew older was better than younger. Quindlen's new memoir, "Lots of Candles, Plenty of Cake," celebrates the upside of aging. You can check out her thoughts in the video above.

We'd also like to invite you to share the moment you knew older was better than younger. It's easy to contribute! You can create your video using YouTube or Vimeo and send the link/URL of the video to themomentiknew@huffingtonpost.com. (Your video submission is subject to our User Terms.) If you create your video using your laptop or mobile phone and have a video file, please attach the file in an email to themomentiknew@huffingtonpost.com.

Please make sure to include your full name with your video submission. Each video should be 30-60 seconds long, and should feature only you, speaking right into the camera telling your story (just like Anna!) Please start your story with your name and the words "The moment I knew..."

We can't wait to hear from you! And if you have any questions, please email themomentiknew@huffingtonpost.com.
