Trust me, you're not the oldest. Monk's post was a reference to the 4 Non Blonde's song What's Up, which I think was released in the early 90's - somewhere around '92 or 93' (unless he's referring to a cover version I'm unaware of).
I'll let you all work out the maths from Monk's statement.
So you're actually a relative spring chicken compared to some of us Eddie (though I look a fair bit younger than I am).
