I'm not sure. Sometimes people say I need to eat more.Even though I do eat a lot. I guess I'm slim. My dad is 5'7" and a half and weighs 130lbs and my mom 90lbs, but she's very small(4'11"😉 I'm taller than her but I'm still young. Ok. I'm not giving you my age, but I'm between the ages of 11 and 14 years. I weigh 78 lbs.
