When you are young, having big boobs might be the best thing ever. You could get more guys, probably feel really good about yourself. But as you age your boobs begin to do something no girl wants to hear: the s word. Your boobs begin to sag, and thats not good. No one wants to see an older lady with her boobs sagging to the floor. You cant still show them off anymore either, no one wants to see that. Instead what was a blessing at first later becomes a curse. Having small boobs means that there isnt much sagging going on, hell, there isnt that much TO sag.
