how to get taller and slimmer?!

you can't really "get taller". But you can get slimmer. Just eat right. There are some websites that tell you what to eat and every thing. Create a daily workout routine and follow through with it every day. Do a waist measurement before you start... then.. like once a week measure your waist. Withing a couple weeks... you'll be slimmer. You don't need to be though... I'm only a year younger than you. and I weigh like 105. No need to worry. Plus...muscle weighs more. So the more muscle you have..the more you will weigh.

Taller = stilts
Slimmer = Run
