1. Thereappearsto be a growinghappiness gap betweenmen and women. Women todayare working more
v v v v v v v v v v v v v v v v
and relaxing less, while men are working less and relaxing more. Forty years ago a typical woman spent
v v v v v v v v v v v v v v v v v v
40 minutes more per week than the typical man performing an activity considered unpleasant. Today,
v v v v v v v v v v v v v v v
with men working less, the gap is 90 minutes and growing.

2. Lead is toxic, but do you know why? Lead is toxic mainly because it preferentially replaces other metals in
v v v v v v v v v v v v v v v v v v
biochemical reactions. In so doingitinterferes withthe proteinsthat regulate blood pressure (whichcancause
v v v v v v v v v v v v v v v v v
development delays in childrenand high blood pressure in adults), heme production (which can lead to
v v v v v v v v v v v v v v v v
anemia), and sperm production. Lead also displaces calcium in the reactions that transmit electrical
v v v v v v v v v v v v v v
impulses in the brain, which diminishes the ability to think and recall information.

3. Aristotlefocused on clarifyingthe concept of virtueitself. He arguedthat it was virtuous to choosethe proper
v v v v v v v v v v v v v v v v v v
amount of emotion and/or action called for in a particular situation and that extremes of emotion and action
v v v v v v v v v v v v v v v v v v
were vices. In all communities there are some men of practical wisdom who have the capacity to judge wisely.
v v v v v v v v v v v v v v v v v v v
Aristotle argued that they have the capacity to follow the "right rule" whatever the situation.

4. Illegal immigrants paylocal sales taxes,and manyof themalso paystate,local,and federal income tax and
v v v v v v v v v v v v v v v v v v
Social Security tax. They also purchase items from local merchants, increasing the amount these merchants
v v v v v v v v v v v v v v v
pay in taxes. In addition, they work for low salaries, which increases the earnings of their employers and the
v v v v v v v v v v v v v v v v v v v
amount of taxes these employers pay. Thus, it is not correct to say that illegal immigrants contribute nothing to
v v v v v v v v v v v v v v v v v v v
the communities in which they live.

5. Numerous studies have indicated that women of color, black women in particular, are over-arrested, over-
v v v v v v v v v v v v v v
indicted, and over-sentenced. African-American women are seven times more likely to be arrested for
v v v v v v v v v v v v v
prostitutionthan women of other ethnic groups. Blackwomen have received significantly longer sentences
v v v v v v v v v v v v v v
for crimesagainstpropertyand served longer periodsin prison.For both murder and drug offenses,
v v v v v v v v v v v v v v v v
Euroamerican women ended up serving one-third less time for the same offenses than black women.

6. It's even more important these days that your computer be protected by a firewall. There are criminal
v v v v v v v v v v v v v v v v
elements lurkinginthe shadows of cyberspace whosend out probes to detect unprotected PCs. Once a
v v v v v v v v v v v v v v v v v
vulnerable computer is found, these criminals install software that assists them in committing identity theft
v v v v v v v v v v v v v v v
and fencing stolen IDs. They also defraud online advertisers by using these zombie computers to visit pay-
v v v v v v v v v v v v v v v v v
per-click ads. v

atmosphere, andthephenomena of the upperatmosphere andthe magnetospherereflect thestateof

abuttingtiger habitat are given a stake in protectingtigers,andthe makers of traditional medicines can be

will be restored, and the immanent extinction of tigers in the wild will be averted.

9. Humans are biological organisms. To understand our behavior and mental processes, we need to understand
v v v v v v v v v v v v v v
their biological underpinnings, starting with the cellular level, the neuron. How we feel, learn, remember,
v v v v v v v v v v v v v v v
andthinkall stemfromneuronal activity. So, how a neuron works and how neurons communicate are crucial
v v v v v v v v v v v v v v v v v v
pieces of information in solving the puzzle of human behavior and mental processing.

10. Viruses are acellular entities too small to be seen with a light microscope. They are composed of a nucleic acid
v v v v v v v v v v v v v v v v v v v
and a few proteins. Viruses replicate themselves and display other properties of living organisms only when
v v v v v v v v v v v v v v v v
they have invaded living cells. Indeed, some viruses can be crystallized and storedin a container on a shelf for
v v v v v v v v v v v v v v v v v v v v
years,but theyretain the capacityto invade cells and cause disease.

11. Harnessing the clean, abundant energy of the sun and wind is critical to solving the global warming problem.
v v v v v v v v v v v v v v v v v
Technological advances have brought the cost of electricity generated bythe wind downby 82 percent since
v v v v v v v v v v v v v v v v v
1981. Solar energy technology has made remarkable progress as new photovoltaic cells have been
v v v v v v v v v v v v v v
developedto converteven greater amounts of sunlight directlyinto electricity. Today the costs of wind and
v v v v v v v v v v v v v v v v v
solar power are becoming competitive with dirty coal-fired plants.

12. It is likely that innocent prisoners in this country have been executed for crimes they did not commit. From
v v v v v v v v v v v v v v v v v v
1973 until 2007, 124 death row inmates have been exonerated. In many of these cases DNA evidence played a
v v v v v v v v v v v v v v v v v v v
crucial role. Yet, in that same time frame, more than 1000 prisoners were executed. For manyof these
v v v v v v v v v v v v v v v v v v
prisonersno DNA evidence was available.If such evidence hadbeen available,how may more would have
v v v v v v v v v v v v v v v v v
been exonerated?
