40 isn't necessarily the expiration date for beauty on a woman. A great deal of women who look good in their twenties look great all the way up into the 40s and sometimes their 50s. I'm dating a woman who's 42 but doesn't look a bit different than when she was 27. It's no surprise J.R. still looks fantastic.
With some women, yes (and men as well)- but on the other hand, there are some pretty rough looking 25 year olds out there... and some pretty damn good looking 50 year olds.
