According to Coed magazine online, these are the TOP 10 Things From Your 20s You’ll Regret When You’re 40! The things you do when you’re young that you’re bound to regret when you’re older.

Do you agree? What regrets would you warn the 20-year-olds about? Leave your warnings in the comments section below…

10. Body Piercing Plugs — Nothing about giant disks in your ears translates well when you’re an honest-to-goodness adult.

9. Naughty Internet Pictures — Pictures from that wild trip to Vegas will either get you fired from your job, divorced from your wife, or estranged from your children.

8. Tattoos — A tattoo (especially one that can’t be hidden) is a constant reminder that you were once a dolt. And, that tattoo’s colors aren’t getting any more vibrant.

7. Choosing Your Best Friend’s Girlfriend Over Your Best Friend — A friendship you and your best buddy had built up since you were six can never be replaced.

6. Getting Married Too Young — Grow up and get rich before even THINKING of settling down.

5. Not Traveling (Enough) — Being older means dealing with heavy responsibilities. Your best bet is to travel as much as you can while you’re single and childless.

4. Not Finishing School — Not having a college degree usually means getting an OK job, doing OK stuff, and having OK things.

3. Smoking — There’s nothing cool about spending the last days of your life fighting lung cancer.

2. Bad Credit — Don’t get greedy and buy a bunch of stupid crap when you can’t afford it. The banks lick their chops every time a stupid 20-something signs up for one of their credit cards.

1. Not Spending More Time With Your Parents — They are the two most important people you have, and they will be gone before you know it.
