I have no one tall in my family, my grandpa was 5'3 lol but to be fair they were poor farmers so i dont think they had the best nutrition
Whats interesting about this is a know several Mexicans who are taller than their parents.
A friend of mine he played football with me but he grew to 5 foot 10 and his Father was an immigrant from Mexico who also worked the fields and he was only 5 foot 4.
You will also see this a lot with Asians, a lot of the American born Asians 2nd and third generations are tall and bigger boned than their parents.
My Korean friend his grandparents are tiny both like 5 foot 3 and foot foot 2, his dad is 5 foot 6 and he is 6 foot 1 with a bigger bone structure.
I think it comes down to nutrition also sleep, sleep is the most imporatnat growth factor that is when our body grows.
I still believe sleep is the key, if anyone has kids here make sure they get at least 8 hours deep sleep in a dark room, that boosts the growth cycle.
Thats what I did, and I think that helped me grow taller I would drink a tall glass of whole milk mixed with several spoons of Ovaltine right before bed.
When I was 14 I did this every other day I would dead hang from the pull up bar outside for 10 minutes to stretch my body loosen it up, before bed.
Every night I would Make a tall glass of cold whole milk with Ovaltine, drink that, for some reason after drinking that Id get sleepy. I would take a piss before bed of course since I drink a lot of fluid and then fall asleep an hour later usually before 9:00 pm.
I never missed a beat
