From: Lethal Weapon Series
Who said it?: Det. Roger Murtaugh
The story behind the quote: The quote comes from the Lethal Weapon movies, specifically from the veteran partner of Martin Riggs (played by Mel Gibson), Roger Murtaugh (played by Danny Glover). During the first movie in the series, Murtaugh, tired from all of his years on the police force, is contemplating retirement. However, he is forced to partner with the suicidal loose cannon Riggs. Although they are of two different personalities, they do eventually form a strong bond of friendship throughout the run of the four films.
The quote is actually the catchphrase of Murtaugh. Every time the pair gets into a hairy situation, he delivers the quote.
Geek wisdom: Age is just a state of mind. Detective Murtaugh is proof positive of this, despite his claims to the contrary. The grizzled detective is always just a few days away from retirement and is getting up there age-wise. Yet, in each installment of the Lethal Weapon franchise, he still manages to do amazing things… things that people half his age would die attempting to perform.
As long as you manage to keep fit, age is just a number. You can do amazing things whether you are old or young.
