The genetics helps.
But I wanna know what he’s been eating. Gotta be something to that...
Probably just decent nutrition. People grow a LOT taller with decent food.
The main commonality in all of the really big people, the 6’8 and up folks is not only a tall dad but a much taller than the average mom. It’s the mom’s genes that can drag them back to the near average. If dad’s above 6-2 and mom’s near 6 foot the kid will almost always be really huge.
He must have a very interesting perspective on life already.
