Don't knock us early 20 year olds 
I was watching the show thinking how good looking she is and then I IMDBed... and got a shock. I thought she was in her late 30's maybe 40. She's doing amazingly well and I hope I can look that good when I'm that age. She maybe a little too skinny for me though but that has nothing to do with age, good on her. As for hooking up with all the men, to me in the show she portrays a 35-40 year old so it's fine. Just ignore her age and go with the flow. Although Laura San Giacomo is only 4/5 years younger too, both very good looking women.
