Growth possible after 21?

[Justintime]

I got the shock of my life today when i was having a physical (life insurance purposes). The doctor measured my height as 6ft. I've always held the assumption that i was 5ft 10.5 and thats how i measured it last time when i was 21.
I'm 29 now and apparently its true, went to my parents place and found the doorframe i last measured 8yrs ago, the 'scratch' was still there and the first thing my mum said is that i definetly was over it. No shoes on and a grade 1 so not artificially enhanced. The new mark was 6ft and a wee bit.

I thought one stopped growing after 18? Should i be concerned?

Did you go in the morning and only measure yourself before late at night? You are taller in the mornings.

Well it was about 2hrs ago i measured at parents, doctors was at about 11am.

Just turned 25 and I'm 5'6"

Not tall but not exceptionally short mate, my dads 5ft 7 and a little and no ones called him short ever.
