In the 1950s, a family who owned a farm near Beulah, Michigan kept a bull chained to an elm (榆树). The bull paced around the tree, dragging the heavy iron chain, which led to a groove (槽) in the bark. The groove deepened over the years, though for whatever reason, it did not kill the tree.

After some years, the family took their bull away. They cut the chain, leaving the loop (圈) around the tree and one link hanging down.

Then one year, agricultural disaster struck Michigan in the form of Dutch Elm Disease. All of the elms lining the road leading to the farm became infected and died. Everyone thought that the old elm would be next.

The farm’s owners considered doing the safe thing：pulling it out and cutting it up into firewood before it died. But they simply could not bring themselves to do it. It was as if the old tree had become a family friend. So, they decided to let nature take its course.

Amazingly, the tree did not die. Nobody could understand why it was the only elm that was still standing in the country!

Plant pathologists(病理学家) from Michigan State University came out to observe the tree. They observed the scar left by the iron chain, now almost completely covered by bark. The plant experts decided that it was the chain that saved the elm’s life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune (免疫) to the fungus (真菌).

It’s said that what doesn’t kill you will make you stronger. Or, as Ernest Hemingway put it, “Life breaks us all, but afterwards, many of us are strongest at the broken places. ”

Some futurologists have assumed that the vast upsurge(剧增)of women in the workforce may portend a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse(反面)of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to putting off
