Sharon is 23, she stands about 5'5" and weighd about 130. Not fat, not skinny.

Per a stat from about 30 years ago, the average weight gain of a married woman is about 10 pounds - as a wife, she cooks - even if she's not hungry.  Okay, so she loses the weight. Two years later 5 pounds creeps back.  Sharon is now 25 and weighs 135.  She continues to battle against the other five pounds - loses two, gains back one, loses 3, gains two...ugh.   Another two years pass, her weight is 133.  

The strip reads a positive.  A few months after the baby is born, she is able to work off 10 of the 20 pounds she had gained.  She is 27 and weighs 145.  Three years later, a few months after the birth of the couple's second child, she's able to get back to the gym, and is being successful at keeping off 15 of the 25 pounds she had gained.  Sharon is 30 and weighs 155 pounds; she is still battling. 

Years pass.  Sharon is 40.  Still battling, and cooking, even when not hungry.  But boy-howdy, it's like she can't cook enough ... where do kids put it all?  She managed to get back into her favorite jeans, and is quite happy.  She weighs 150, and hopes to atleast lose ten more.  An even more intense battle, like rolling a rock up an incline.  But she wages on.

Sharon is 60.  While the heat flashes were few, and the mood swings even fewer, boy did the change of life affect her metabolism.  Still hitting the gym, Sharon weighs 160.  Those favorite jeans have long been deposited into the goodwill box.

She started out at 130, and is now at 160.  This happens to women.  We gals are prone to weight gain.   It's called life in the real world.  Even to women who put in the work to keep their weight under control.  Please note, she gained 30 pounds over the last 35ish years.  Not 80.
