liver function

It's May and I'm in England. The sun is shining brightly, the oak trees are out before the ash, which is hopeful (Oak before ash we're in for a splash, Ash before oak we're in for a soak), and the green fields here on my friend Pauhla's organic farm are full of healthy lambs. I am walking down the lane with Doug the Collie, who at 18 months old needs time out from his brother and sister and a little special attention to keep him on the track to being a good citizen.
