Hi there , i'm 21 years old and my height is 5'5 and i weigh about 47 kg , which means i'm under weight as well .please help?

Refocus: At your age, you are not going to get more height. Although tall is a plus for a man, it's more important that a man look physically fit at whatever height. Lee priest (photo) who i've met is 5'3"; hartthrob michael j fox 5'4". A few hours a week in the gym will make you the envy of any tall guy with a paunch. A shorter man is less threatening and may be preferred as a friend / buddy.
