This should be in Wannabes....!
HZ123 I think it could be worse than you suggest. All other British airlines allow captains to work to 60, but many allow pilots to go on to 65 in the right hand seat. The legislation I think you're indirectly referring to is intended to make it impossible to retire an employee simply on grounds of age, so you may find BA co-pilots going on into their 70s!
Now, if we can persuade the USA, France, Italy and (I think) Portugal to give up their unreasonable prohibition of captains over 60, there may never be another BA sponsorship!
