My age is 24 yrs. But I don't look as my age. I look like teenage, like 17-18 age. I look junior in my all friends group. I also don't have beard. Is this normal? Or any health relation issue? Please help me I am worried. #note: height 167 cm weight - around 60 kg. I don't have any major illness in my body. I am a student. I don't usually do any stressful hard work. Do fitness workout- rare.
