Getting tough

My grandfather worked in a blacksmith shop when he was a boy, and he used to tell me, when I was a little boy myself, how he had toughened himself up so he could stand the rigors of blacksmithing.

One story was how he had developed his arm and shoulders muscles. He said he would stand outside behind the house and, with a 5-pound potato sack in each hand, he would extend his arms straight out to his sides and hold them there as long as he could.

After awhile, he tried 10-pound potato sacks, then 50-pound potato sacks. Finally, he got to where he could lift a 100-pound potato sack in each hand and hold his arms straight out for more than a full minute!

Next, he started putting potatoes in the sacks.

U.S. Daylight Saving Time

In 2007, Daylight Saving Time in the U.S. ended at 2 am, the duration of DST during the year having been extended by Congress under The Energy Policy Act of 2005 to run from the second Sunday in March 2007. Since 1986, U.S. DST had applied from 2 a.m. on the first Sunday in April to the last Sunday of October (with some differences under state laws). Effective in 2007, DST was set to begin on the second Sunday of March and end the first Sunday of November. In the European Union, Summer Time began as before with all time zones changing at 1:00 am Universal Time (Greenwich Mean Time) on the last Sunday in March and ended at the same time on the last Sunday in October.«
