No, i don't have. In fact i really wanted to be fat. It's just that my metabolism works fast even if i ate a lot. I eat three meals a day and also snacks, yet i am still thin. Fortunately, i am not sick and i don't experience colds for how many years. With that i could say that i have a strong immune system. Even if that so, i am still thankful and very grateful to what i have, for what God has given me.
