    For a long time, the smartwatch industry had just a few big companies that could set any prices they wanted and kept cheating customers. But now one new tech company is turning the $5 billion smartwatch industry on its head. The company called OshenWatch has found a way to offer a far advanced product at a part of the original price.

Let’s meet the OshenWatch. OshenWatch combines the functions of a fitness band （手环）， digital watch, and health monitor all into one. It feels comfortable to wear. Even better than some of the expensive smartwatches I own from other big tech companies. Extreme indoor and outdoor sports? No problem, the hardened aluminum shell （铝壳）and the lowered-temperature touchscreen glass won't break easily even if you tried.

In my opinion, the OshenWatch is the next generation of smartwatches. Take calls, sleep monitoring, show incoming messages, etc…The watch has all the basic functions that a good smartwatch must have and much more.

What makes the OshenWatch so popular? The green laser （激光）behind the watch is the secret! It is the heart rate monitoring function. This watch lets you measure your blood pressure, heart rate, blood oxygen level, calculate your beats per minute. Give you extremely important time to catch problems early, and seek medical help before it's too late.

This is the reason why the OshenWatch will be the best-selling smartwatch of 2020. No other watch is that advanced. It could actually save your life one day!

    Born in 1918, in the little town of White Sulphur Springs, West Virginia, Katherine Johnson was simply attracted by numbers. As a child, she counted everything. She counted the steps to the road, the steps up to church, the number of dishes she washed …By the time she was 10 years old, she was a high school freshman, which was truly amazing in a time when school for African-Americans normally stopped at eighth grade. To meet her math potential （潜力），her father drove his family 120 miles to Institute, West Virginia, where blacks could continue high school education. Johnson's excellent performance proved her father's decision was the right one: Katherine skipped grades （跳级）to graduate from high school at 14 and from college at 18.

1953, after years as a teacher and later as a stay-at-home mom, she began working for NASA, which began hiring women to measure and calculate the results of wind tunnel （风洞）tests in 1935. In a time before the electronic computers, these women were called "computer". Even after NASA began using electronic computers, the astronaut John Glenn requested that she should personally recheck the calculations made by the new electronic computers before his flight.

She continued to work at NASA until 1986. Her calculations proved critical to the success of the Apollo Moon landing program and the United States' journey into space. Her story was the basis for the 2016 film Hidden Figures.

Katherine Johnson, a great mathematician, physicist, space scientist and the last computer that wore skirts, passed away on February 24, 2020.

Sons who have fond childhood memories of their fathers are more likely to be emotionally stable in the face of day-to-day stresses, according to psychologists who studied hundreds of adults of all ages.

“As our study shows, fathers do play a unique and important role in the mental health of their children much later in life,” Psychology professor Melanie Mallers of California State University said.

For this study, 912 adult men and women, who were between 25 and 74 years old, completed short daily telephone interviews about that day’s experiences over an eight-day period. The interviews focused on the participants’ psychological and emotional distress (i.e., whether they were depressed, nervous, sad, etc.) and if they’d experienced any stressful events that day. In addition, the participants also reported on the quality of their childhood relationships with their mother and father.

People who reported they had a good mother-child relationship reported three percent less psychological distress compared to those who reported a poor relationship, according to Mallers.

Men who reported having a good relationship with their father during childhood were more likely to be less emotional when reacting to stressful events in their current daily lives than those who had a poor relationship, according to her findings.

Also, the quality of mother and father relationships was significantly associated with how many stressful events the participants confronted on a daily basis. In other words, if they had a poor childhood relationship with both parents, they reported more stressful incidents over the eight-day study when compared to those who had a good relationship with their parents.

Mallers theorized why healthy or unhealthy relationships may have an effect on how people handle stress as adults. “Perhaps having caring parents equips children with the experiences and skills necessary to more successfully navigate their relationships with other people throughout childhood and into adulthood.” she said.
