Yeah take what the AFCO tell you with a pinch of salt sometimes, told boy in our room to join up and when he has passed basic training he can re-trade to be a PTI (couldn't at the time due to age restrictions). He soon found out that wasn't true.
Edit - We also have a guy in our room thats 28, going through TG4 (ICT) training just now and he gets on ok. 29 is not too old.
