A temporary lapse of memory as a person ripens in age: The couple in their golden years realized that they were often experiencing senior moments because they couldn't always remember some well-known word or name when they were talking to each other.

Rick Perry, a 65-year-old governor of Texas and a Republican candidate for President of the U.S. in 2011, apparently had a senior moment or "brain freeze" when he stopped in mid-sentence while struggling to remember the name of the Department of Energy as one of three federal agencies he had often said should be eliminated.

Perry's senior moment resulted in a pained look on his face as he stammered and started over again but he still couldn't remember what he wanted to say; so, he changed the subject after a 53 second senior moment.
