Has Lt. Columbo's age ever been revealed, inferred, or commented upon?
I was reading the Wikipedia page for the character and a lot of small details were found in episodes that I found very obscure (e.g. Columbo makes a single joke that is the only reference to the character also having a glass eye). However, I couldn't find how old the character was supposed to be at any point in the series. I was hoping maybe it was commented upon in the later stuff (TV movies?) which I am not so familiar with, but couldn't find anything there either.
