There is no 'Average weight' as you pt it, your weight is dependant on multiple factors not just diet and exercise, there are things like genetics, environment that you live in, I was 6 foot 2 at 15 and I weighed 160lbs so your doing good, just try to not eat too much indulgence food and you will be fine.
Hope this helps :)
False, 81lbs is not a normal weight for a human baby but normal for a rhinoceros baby
37kg 81lbs
There isn't an exact weight that you "should" be. It is better to see if you fall into a healthy range category, according to your sex, age, and height. A healthy weight for you would be between 81lbs and 120 lbs.
On Saturn, you'd weigh 93.15 pounds.
