People often say about other people in high school, college or their 20's, that looks aren't important because in 20 years, they're just going to fade away.
First of all, 20 or 30 years is a long time.
I know people in their 50's and 60's who look just as good as people in their 20's. I know a 70 year old guy who looks VERY good, and not just for his age.
You can look good through age. You just can't be lazy. If you go the gym, eat healthy, dress well and use a few cosmetics, you can look great at 50 or 60.
This is just used by people in their 20's who are in bad physical shape or feel insecure about their looks to justify the fact that there are people their age more successful in dating than they are.

It's definitely not a given that you will lose your looks when you age.
Like you said, people simply can't be lazy on upkeeping themselves.
One with little to no upkeep may look good NOW, but in their 30s, their looks will fade if no effort is done to maintain oneself.1
