I think I saved a life today. The life of a furry, dark brown field mouse, which technically is a meadow vole. Despite temps of 18 degrees, the critters were tunneling through the snow on a sweeping alfalfa field near here.
Wiley, my dog, sniffed one out and was using her snout to toss into the air. I hope I intervened in time. I called her to my side. The mouse raced away. Whew. That was a close one.
On a little larger scale, yesterday I donated a pint of blood. It's a common type, B+, and there's rarely a shortage. Yet, a recent news story reminded me it can still be of use as plasma, sometimes used to treat burn victims.
Just think: Scientists have successfully cloned pigs and sheep. But they still haven't found a substitute for the sticky, red life pulsating through our veins.
