Exercise and TV Watching May Affect Sperm Count 

Here's some news that may cause men to drop the remote controls and hit the gym: Excessive TV watching and a sedentary lifestyle has been linked to lower sperm counts, according to a study published Monday in the British Journal of Sports Medicine. Researchers in the Harvard School of Public Health analyzed 189 healthy men between the ages of 18 and 22, and noted the number of hours per week they exercised, as well number of hours per week they watched TV, videos, or DVDs, over the past three months. The results? The men who were the most physically active, and spent 15 hours or more exercising each week, had the highest sperm counts. In fact, this group's sperm count was 73 percent higher than that of the group who exercised the least, BBC Health reports. Additionally, men who spent 20 hours per week or more in front the boob tube had a sperm count 44 percent lower than those who spent little time in front of the TV. The study was a relatively small one, but it echoes a tip that works for our overall health and, apparently, for sperm counts, too. "My advice would be everything in moderation," Allan Pacey, head of andrology for Sheffield Teaching Hospitals in the United Kingdom, told BBC. "And that includes time in the gym as well as watching TV."

Harbaugh Brothers: A Healthy Sibling Rivalry?

After a ferocious Super Bowl, John Harbaugh, whose Baltimore Ravens emerged victorious over his brother Jim's San Francisco 49ers, embraced his sibling on the field. John reportedly told his brother he loved him, and Jim said congratulations.

That bittersweet reunion amid one of, if not the, most intense competitions in American sports, may perhaps serve to inspire the countless people whose relationships with their siblings leave a lot to be desired.

The relationships we have with our siblings are typically our longest ones in life. But very often, they are filled with conflict. In fact, 44 percent of adults admit to "serious contentions" with a sibling, and such unresolved strife amounts to the leading source of regret late in life, says psychotherapist Jeanne Safer, author of Cain's Legacy: Liberating Siblings from a Lifetime of Rage, Shame, Secrecy and Regret. "It's one of the last taboos," says Safer, who herself was estranged from her older brother. [Read more: Harbaugh Brothers: A Healthy Sibling Rivalry?]

Want to Sleep Better? Unplug First

Are you having trouble falling asleep? You may have an overactive mind from all the electronics in your life, writes U.S. News blogger Keri Glassman. Phones, Facebook, TV, blogs, e-readers—electronics have become such a constant part of our daily lives that we feel almost lost without them. But it's hard to wind down and nearly impossible to get a good night's sleep when our brains are all wired up!

Experts suggest giving yourself a curfew for electronics to prepare yourself for a full night of zzz's. At least a half hour before you want to fall asleep, power down all your devices, and even keep them in another room. (Yes, your does smart phone does have an off switch.) Exercise your right to shut off the world and enjoy some peace and quiet.

Yes, we all have busy lives, but no good will come from fooling ourselves into thinking four or five hours of sleep is enough. Don't skimp on sleep, because that's when our bodies crank out important hormones that help repair cells and tissues, fight off infection, and boost our immune system.
