What the world's best-preserved mummy shares with Madonna, Elton John and Lauren Hutton

Ötzi (not his real name) lived on the Italian/Austrian border 3,300 years ago near the crest of the Ötzal Alps.
     He was 45, plus or minus 6 years and had a 3mm gap  between his two upper front, teeth a condition which Madonna, Elton John, Lauren Hutton and Alfred E. Neuman also have, called diastema.
     Investigators know a lot about his murder, the coldest of cold cases, since he was on (well, in,) ice until 1991, when global warming thawed him and he was discovered by two hikers.
