Some people age gracefully, most people don’t. As for what may have caused her situation, there’s probably plenty of contributing factors. Being a member of the Fonda clan, growing up in Hollywood, health problems, etc. are probably the biggest contributors. Regardless, she was beautiful in her youth, like most people. Again aging is not kind in many ways and too bad her privacy has now been disrupted. The voyeurs most likely will not leave her alone until she leaves this world. The price of celebrity and being in a famous family is most often too high a price to pay. For what it’s worth, her eyes remain kind and those are the windows to the soul, eh?
As far as I know she’s not sitting in an enemy anti-aircraft gun or betraying American POWs so what ever she’s up to is none of my business.
