How do you know when you are done growing? ...
Answers: Heightwise it will be when you start shrinking.
A lot of people stop growing upward and start growing outward!
But seriously;
For most folks, elevation growth will stop by age 21. Although, a friend noticed he outgrew his shoes at almost age 24. He went from size eight to size 10 contained by one year. Foot doctor told him it was not adjectives that unusual for someone who carried a lot of consignment while walking. He was contained by the army artillery and carried 200 pound shells on his shoulders about 40 times a morning! So his body decided it needed bigger foot to handle the stress!!!
wen ur 21 for a reality
