Long time no post.
I just measured myself for the first time in about 6 months and discovered I'd grown half an inch (I'm now 6'3.5" when I stand perfectly straight). I just turned 21 last week. Is it reasonable to believe I might hit 6'4? My Dad is 6'5.5 and my mom is 5'9.
Personal anecdotes about growing after 21 welcome .
