The RAF Pension Payout Dept reccomend sitting all day watching horse racing whilst eating burgers and drinking to excess whilst for breakfast cornflakes and fresh double cream is just the thing. An evening snack of an 24 pack of Walkers Crisps and a few double whiskies will complete the diet! Every month or so take sudden exercise or a hike up a munroe till you feel chest pains, pushing on a little futher will help them go away!
