So many people bang on about health, but don't really do anything about it. The healthiest vegetables are things like stinging nettles, dandelions, thistle roots, and bramble shoots, and they are all free if you are prepared to get some exercise by collecting them. Health doesn't come out of a bottle, or a needle stuck in your arm. It come from speeding up your metabolic rate by walking faster, and taking the stairs, and by walking erect to avoid neck problems.
