can i still grow taller? i'm a 19yrs male and 178cm tall.

my dad is 173cm, my mum is 155cm and my brother is also 178cm.

my brother was a basketball player, but i did skipping a lot when i was younger. i drink two mugs of milk daily. i sleep at least 7 to 12 hours. i've been going to the gym. i eat 3 - 5 meals daily.

i've been growing 4 inches each year during elementary school .. and grew hardly an inch during high school. i'd my first wet dream when i was 11yrs, so i guess that's when puberty begins. that was also when i started to grow more hair.

what else can i do to grow taller ..
