Seven Days with Lot

Remember Lot? He is the main character in the biblical story of the destruction of Sodom and Gomorrah. Why does Lot choose to live in Sodom? When God says He is going to destroy the city because of its wickedness, why do Lot and his wife hesitate to leave? In His mercy, God sends His angel to lead Lot, his wife and his two daughters out of the city. When the angel tells them to flee to the mountains, Lot pleads to go only as far as the small town of Zoar. Only three of them arrive there safely before God rains fire and brimstone on the land. What happens to the other one?
How do they spend the rest of their days? What is Lot's legacy?
From the name Sodom, we get the word sodomy. What is Sodomy? What is incest? Lot's story, which contains both, is not meant for children.
