So I'm a 16 year old teenager of 167cm height but compared to my classmates, I feel a bit short, & I really want to get taller, any advice on that?
Maybe you just grow some later than average. Nothing much you can do about it. Al you need is patience....
Use that rack they used in the middle ages ( 1200 to 1500 ) where your hands were tied above you as you layed down on a flat bed and your legs were tied at bottom and you were stretched. Do you need any help.
Use that torture device that stretches people
Most men grow up to the age of 28, so time. If you become an astronaut, and spend some time in space, the lack of gravity will make you a little taller.
