Um...maybe...like 1/4" to 1/2".
I think so!
Usually you don't stop growing until your mid 20's
Yes--I have an Uncle that grew a few inches in his early 20's.
Yes. A few people with certain conditions will even continue to grow through their entire lives -- unfortunately that almost always means their lives will be fairly short.
My boyfriend grew some more after 18, he was 20 and he had a growth spurt. He went to the doctor and was told it was normal, some people don't stop growing until age 21.
My uncle did but none of my aunts. I think ive shrunk.
Yeah my eldest youngest brother is 19 and he's still growing, although starting to slow down.
