I'm just 24 years old but my friends say that i look like 30 years old man.. why is it so? and how do i need to overcome this?

Several issues: beard and mustache are good looking but add look of maturity. Make sure you sleep well, exercise, and eat a balanced diet. If you smoke, another reason to avoid is because it tends to age skin faster. Ultimately, if it is just your features and the way you are put together, just be proud of who you are. True friends care about who you are on the inside.

What do you think: First what do you think do you look like a 30 years old man. Second I suggest to find a new Freind , people who have Freinds like that do not need enemies. Third do you have any medical problem that will make you look older. Last exercise daily that always work and eat healthy and lose weight if you are overweight last smile and be happy sadness and stress will make anybody look older. Good luck.
