No.. no.. really - it's official, your mother knew it all along. Cod Liver Oil will prevent you from needing a knee replacement and keep you running/power walking into your nineties. Well OK, the research doesn't actually say that, but it stands to reason it's WD40 for the joints. We keep on taking the tablets (high strength obviously) - just in case. Better than the stuff your mother made you take on a teaspoon. Read all about it here.
BTW new toy - macro lens. Rainy days hold no fear - which is just as well given the forecast for the weekend. You will be viewing the contents of the kitchen drawer whenever it clouds over. Bring it on I hear you say :)
