Modern Human Variation: Distribution of Blood Types
http://anthro.palomar.edu/vary/vary_3.htm
Blood type distribution shows a different, and more complex genetic history than so-called racial categories.http://www.magnetnerd.com/Neodymium%20Magnets/Dirks%20Accident.htm
Dirk had an accident. Below is the X-ray showing his totally crushed finger tip. It took 1 1/2 hours of surgery to remove the shattered bones and repair the damage. Medically speaking, he crushed his right index finger distal phalange. The magnets had a 50 cm (20 inch) separation when they decided to fly together.
