Celebrities like to keep secrets, and their favorite secret to keep is how old they are, because we'll assume they're 25 for the rest of their lives if we don't know their actual age. (sarcasm)
In an effort to keep Hollywood's age a secret California has passed bill AB-1687 which forces sites like IMDb to remove the age of an actor from their page if the actor requests it.
This bill was supposedly put in place to protect actors from age discrimination, assuming casting directors look on sites like IMDb for info on potential hires and might pass due to their posted age.
But the bill doesn't apply to news outlets, so an actor's true age will still be easy to look up online, which makes this quote from Larry Gelbart just as true today as it was in his day:
