"The lovely thing about being 40 is that you can appreciate 25 year-old men"
"I'm 40 and I feel great. Feel for yourself !"  
"Few women admit their age. Few men act theirs"  
"Middle age is when you still believe you'll feel better in the morning."

"A diplomat is a man who always remembers a woman's birthday but never remembers her age."
"A well adjusted woman is one who not only knows what she wants for her birthday, but knows what she´s going to exchange it for."
"One should never trust a woman who tells her real age. A woman who would tell one that would tell anything."  
"We know when we´re getting old when the only thing we want for our birthday is not to be reminded of it."
"Love your 40's, because you know what comes next? Your 50's !"
