Barbie's Real Age

So... I was in the shower just now, and I was thinking about the next Barbie I will be featuring. That got me thinking about Barbie's actual age. Sure, we all know her 'official' age is 54, since she came out in March of 1959. BUT... when she came out, she was billed as "The Teen Age Fashion Model". This means she could have been as old as 19 when she came out, meaning that she could actually be as old as 73 now. It's true that some women lie about their age! She certainly looks great for a senior citizen!
