Bex88 I've been retired from BA almost as long as you've been alive, so all I can say to you as a very lucky 35year old with a command don't even consider unless you require a long period in your life that you will regret forever!
With respect, having been retired as long as you have perhaps you don't have the most up to date information to be able to give someone such blanket advice. For example, you never had to deal with the bubble situation that Bex88 is caught in (which is of massive importance). Not to mention the raft of other changes in the meantime.
Bex88, I can only offer the same advice that has been given. Look at the options, gather as much information as you can (particularly recent first hand experiences), consider things like part time, moving, commuting. Try to be honest with yourself and then choose the best option for you and your family.
Good luck.
