The UK should bring back National Service for people aged 65-68. After all if some future Government wishes to send the Army on a "Peacekeeping Mission" in Afghanistan it's hardly fair to send young people on patrol because, God forbid and they get blown up, they will really miss their legs and gentlemens parts.
On the other hand if a couple of 65 year olds lose some of their lower bits through an IED they will not mind as much because they have had a good chance to employ them.
This would also mean Tony Blair and Gordon Brown would be eligible for service.....
