Is it ever too late to "balance" yourself?

[Cass]

I understand a lot of your balance and co-ordination is gained when you're a child, much the same way your ability to learn skills decreases with age.

I'm 19 at the moment (young by life's standard, I know) however as far as gaining balance and co-ordination at a peak rate, have I missed the boat?

No I'm 40 in two weeks and my balance it getting better and better. Do core stability exercises which will help enormously.
