Abstract paper clip wiggle. On glass. (we are still making things).
There was a certain geometric perfection in our theory, a simple habit, made regular and easy, to fend of colds, flu and the hostile bugs. Eat yogurt every day that you live and as far as possible breathe. It worked so well for a year or more. Then the yogurt eating stopped, sudden as a door slam, replaced with a fine strain of rough Celtic porridge and honey from the bums of the best bees. Alas. I now have a cold, a stinker and Ali too but I've bought a weeks supply of bacterially perfect yogurt and blue milk.
