You have eased my mind Pete. When there was no replies I feared that I had given concern to folk. I know how I felt when I saw the picture, I feared the worse and went to my doctor.
Friends. Don't bottle up fear or reach for pills or take to your bed. There is a perfectly reasonable explanation. My doctor called up the picture on his computer and initially suffered the same alarm, his face went white, he had to loosen his tie and he began to take his blood pressure. I didn't get all he said but he explained that he had been on call all that last night and was sure this was nothing that a good nights sleep would not cure. Showing me the door he said, "Go and get some sleep and stay away from that picture."
Well, it worked! Please forgive me for omitting to add this before posting the link to the picture.
Please don't get worried. If, as I did, you saw a dolphin and two camels, Hooray! You are normal.
