5'9 ladies!!

I"m 5'9 and 192 lbs but going for 160 to be able to join Army ROTC and receive a scholarship. I have a twin sister who is 5'9 and 140 lbs and she is always nagging me about my weight and telling me she has no problem with getting into rotc because she skinny so its nice to see other 5'9 ladies that support each other instead of bring them down.
