10. "You'll Be Married in 5 Years."
Even though we live in progressive times, people still imagine themselves being married by the time they hit their late 20s. If you don't, your grandmother certainly does. The truth is that you might be a few relationships away from the sick bachelor party and disappointing honeymoon we all dream of. You could wake up one day and find that the spark is gone, or you could be transferred to Anchorage for work and realize that your relationship can't take the distance. At any moment, you can find yourself thrust back into the dating scene. The good news is that many of your friends will still be single, and with the ever-increasing divorce rate, you'll find that new friends are joining you in bachelorhood every day. By time you're 30, you'll have the same size dating pool you had when you were 20. And this time around, it's a lot easier to get laid.
Sure, you won't have the body you had when you were 20, but thankfully, you won't have the mind you had at 20 either.
