2. Hemingway was not just a hunter and fisherman (and a more than passionate one) but was also a fan of... cooking. Not only he cooked rather well, and sometimes his "creations" were amazing, but he also collected recipes from all over, and liked to try them, change them and experiment with the ingredients.
3. In his early years his mother forced him to learn to play the cello, and Hemingway disliked the mere idea so much that he opposed it with all his might and turned every hour of practice into a parody. It took a lot of time for his mother to abandon the idea, and for all those days the future writer simply hated the cello and to a large degree music itself.
4. He preffered to type standing up, having his typewriter on a suitable chair or tall table. He could do it for hours, without a pause, and made his notes and corrections in pencil.
5. Starting with 1981 in Key West, Florida, USA, you can take part in an unusual lookalike competition, where you can be the next Hemingway copy. Or lookalike. You need to have a white, impressive beard, of course.
