-all the movie stars you're attracted to are now younger than you.
-9 times out of 10 when you meet someone new, they're younger than you.
-bending down to get on the floor and then getting back up is a lot more challenging than you remember.
-you remember when those lame, raunchy teenager movies were what you and your friends went to see on the weekends.
-most of the time you'd rather stay home and watch t.v. or read a book instead of going out to the bar.
-you walk into a room and immediately forget what your purpose was in going there.
-you sometimes know exactly what you want to say but cannot for the life of you remember the word that MEANS it.
-you're married.
