Have you seen people in there 60's lately? lol it's not that weird for them to look younger than that by past standards thanks to human evolution and genetic diversity, for example in the 80s-90s it was super rare for someone to live to be 100, but now it's a constant, and because people are living so much longer their bodies degrade slower, look at Andie MacDowell, she's 63, Jamie Lee Curtis as well. hell kim cattrall is 65 lol. it also has to do with the work that's put in, nana is rich enough to buy a house and furnish it at the drop of a hat so i'm sure she can afford all kinds of skin care, plus has a best friend whose a doctor and exercises regularly. so I'm pretty sure when it comes to keeping herself lookin good, nana got it on lock. and what her genetics can't do, she can do financially lol. though for me personally, I would say she does look about right for her age myself when she isn't wearing makeup. but that's just me
