Assuming all thing's personality is equal for the men, women may fall under one of two categories:
- Those who prioritize the bag
- Those who prioritize (physical) attraction
If the bag is her priority, age and physical attraction obivously take a backseat. The more bag-conscious they are, the flabbier and wrinkly the dude can be.
On the flip side: a dime piece 22 year-old who's priority is physical attraction (i.e. someone that makes her go

on sight), there's no "age" per se, but if a 6 six pac and full hair is her thing.. yet by 35 you're fat and balding... well... those are the breaks.
But of course women, like men, have their preferences when it comes to physical attraction. Some may like bald, or rugged with a bit of gray.
In general, i'd agree that by mid-30s is when you're at your limit, simply bc not many dudes can keep ish together consistently after that, unless you're a baby-face and/or stay in great shape.
