To put a little persepective on things with Hammnond.
They said it look at least 10 mins of extracation time. That is 10 mins without proper oxygen support.
They say 3 mins is a reasonable amount of brain 'time' before it starts to get 'injury'.
I realise I'm someone who takes the 'darker side' on things at times, but having dealt with a VERY similar accident only 18 months ago, I do know what the potential outcomes are here.
I'm not saying he can't make a full recovery, but just trying to let people know that 100% recovery seems unlikely from the information given. That doesn't mean people can't walk and talk - it means that people are not necessarily the 'same' people that we all remember (if that makes sense ??).
Anyways - fingers crossed.
Rgds,
