Genetics play only 25% role in it. My father was only 5 6 and my mother is just 5 4 and my brother is 6 1
It is the consequence of the medicine. Once my brother had a minor polio attack when he was just 12 years old and doctors told my parents that he can not grow taller than that (hardly 5 ft). He used that medicine for an year and he is now 6 1.
This is more than an evidence.
Can we grow wings by hanging for 24 hours a day?
(Can anyone tell me exactly how to write the feet and inches mathematically. I've forgotten Maths after entering medical field lol :) )
