Obstructive sleep apnea, in which people stop breathing for short periods while sleeping. Breathing pauses last from seconds to minutes and may occur 30 times per hour, after which normal breathing then starts again, often with a snoring or choking sound.

About five percent of adults have some form of sleep apnea. It can ncrease the risk of high blood pressure, heart attack and arrhythmias. It is most prevalent in obese people and some studies have also postulated that obstructive sleep apnea may be linked to cancer because of low levels of oxygen in the blood. 

In some women abnormally high levels of the common and pervasive chemical perchlorate may lead to adverse effects in their offspring. The study in the Journal of Clinical Endocrinology  &  Metabolism says is the first of its kind to shed light on the possible harmful side effects of perchlorate in mothers and their children.  

A long-term, large-scale population-based study of individuals aged 55 years or older in the general population researchers has found a four-fold increased risk of developing dementia or Alzheimer's disease (AD) if they were diagnosed even with mild cognitive impairment (MCI).

Compared to cognitively healthy individuals, other risk factors including older age, positive APOE-ɛ4 status, low total cholesterol levels, and stroke, as well as specific MRI findings were associated with an increased risk of developing MCI.  

A new hand-held device uses lasers and sound waves to accurately measure how deep a melanoma tumor extends into the skin, providing valuable information for treatment, diagnosis or prognosis. 

Studies have shown that being a 'night owl', like people who claim to multitask, is something of a myth - people perform better in the mornings whether they are night owls or morning people people - and a new study finds that becomes more pronounced with age.

Older adults tested in the morning not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to a study in Psychology and Aging. The authors say this some of the strongest evidence yet that there are noticeable differences in brain function across the day for older adults.

Baby Boomers, a trend in births that happened when soldiers returned home from World War II, started off their lives being critical of American culture and having a sense of entitlement about how the world should reshape itself to suit them. But now, compared to Generation X and Millennials, they may be the last group with a true sense of responsibility.

While Generation X got validation from Winona Ryder characters and Millennials claim to be above working because rent and health insurance is handled by parents, Baby Boomers continue on because they must - even when it comes to the gym.
 
Few seem to enjoy it, they instead know they will be worse off later if they don't make the effort now.
