A chest CT scan is a more detailed type of chest x ray that takes many detailed pictures of your lungs and the inside of your chest.
Greece fell when the Roman Empire envaded Greece and changed their religion. Wasnt a good Idea though. I'll Say! I mean even though it was reletively the same, same gods different names, and the same legends, just from a different point of view.
It does snow in Greece. Not more then once a season in Athens or the islands, in fact rare enough for it to be a major event. However it does snow in the mountains so much that you can ski there. The last few years I have gone to Greece for Christmas, January and February and some days the weather was beautiful.
