Doppelgangers

In 1979 University of Minnesota psychologist Thomas J. Bouchard studied a pair of twins, Jim Lewis and Jim Springer, who had been separated at birth. Here’s what he found on interviewing them at age 39:

  • Both men had had first wives named Linda, divorced them and married women named Betty.
  • Lewis named his first son James Alan; Springer named his James Allan.
  • Both named their dogs Toy.
  • Both had worked as gas station attendants and for the same hamburger chain.
  • They drove the same type of car and bought the same brands of cigarettes and beer.
  • They regularly took annual vacations at the same Florida resort.
  • Both disliked baseball but enjoyed stock-car racing and woodwork.
  • Both gained and lost weight at the same age, bit their fingernails compulsively and had had a minor heart attack.
  • Both suffered from migraines.

“Our findings continue to suggest a very strong genetic influence on almost all medical and psychological traits,” Bouchard said. After an extensive study of separated twins, he concluded that shyness, political conservatism, dedication to hard work, orderliness, intimacy, extroversion, conformity, and a number of other social traits are largely heritable.

The coelacanth, a prehistoric fish, was thought to have died out 65 million years ago — until a museum curator noticed one in a South African fish catch in 1938.

When a second specimen appeared in 1952, prime minister Daniel François Malan exclaimed, “Why, it’s ugly! Is this where we come from?”

Point Nemo

If you want to be really, really alone, head for 48°52.6’S 123°23.6’W in the South Pacific Ocean. That’s “Point Nemo,” the point in the ocean farthest from any land. You’ll be in the middle of 22,405,411 square kilometers of ocean, an area larger than the entire former Soviet Union.

The point on land farthest from any ocean is at 46°16.8’N 86°40.2’E, outside the Chinese city of Urumqi, in the Dzoosotoyn Elisen Desert. It’s 1,645 miles from the nearest coastline.

“The Beech Tree. — A Nonconductor of Lightning.”

Dr. Beeton, in a letter to Dr. Mitchill of New York, dated 19th of July, 1824, states, that the beech tree (that is, the broad leaved or American variety of Fagus sylvatiea,) is never known to be assailed by atmospheric electricity. So notorious, he says, is this fact, that in Tennessee, it is considered almost an impossibility to be struck by lightning, if protection be sought under the branches of a beech tree. Whenever the sky puts on a threatening aspect, and the thunder begins to roll, the Indians leave their pursuit, and betake themselves to the shelter of the nearest beech tree, till the storm pass over; observation having taught these sagacious children of nature, that, while other trees are often shivered to splinters, the electric fluid is not attracted by the beech. Should farther observation establish the fact of the non-conducting quality of the American beech, great advantage may evidently be derived from planting hedge rows of such trees around the extensive barn yards in which cattle are kept, and also in disposing groups and single trees in ornamental plantations in the neighbourhood of the dwelling houses of the owners.

In 1983, the Journal of the American Medical Association called for a ban on boxing. The editor, George Lundberg, called boxing an “obscenity” that “should not be sanctioned by any civilized society.” Since then, the American Neurological Association, the American Academy of Neurology and the British, Canadian and Australian medical associations have also called for abolishing the sport.

Among boxers with 20 or more professional fights, the AMA says three out of four show brain deterioration.
