Women are Fairer than Men
According to a new research, women of European descent are actually twice as likely to be blonde than men. The new genetic study is the largest one conducted and researchers looked into nearly 300 000 people of European descent. They found that 124 new genes played a great role in determining the color of our hair.
Researchers said that they are not sure why women tend to be blonder than men. The authors of the study call it an “intriguing mystery.” Prof Tim Spector, lead author said: “It’s a mystery and it’s intriguing because it wasn’t what we were looking for. We thought it was a bias but it wouldn’t go away and it’s found in every sub-group of every population we saw.”
The study was conducted by the American DNA testing company 23andMe, the UK Biobank, and the International Visible Trait Genetics Consortium. Also, their study partners are from Australia, Netherlands, and Italy.
This opens up a whole new area for researchers to discover why there are some significant difference between men and women when it comes to the fairness of the skin and color of hair.
Prof. Spector has some theories: “We thought it might have something to do with the attraction of women for darker skinned men and vice versa – but we don’t think the genes are any different. We think the genes are being expressed differently – so for some reason, the blonde genes that may be there at birth are persisting in females and disappearing in males.”
Excessive Drinking can Take a few Years of Your Life
According to a major report, excessive drinking can take a few years of your life. The study of 600 000 drinkers estimated that those who have between 10 and 15 alcoholic drinks each week could shorten a drinker’s life by one or two years. Furthermore, people who have more than 18 drinks a week could lose four or five years of their lives. According to some guidelines in the report, we should not have more than six pints of beer or seven glasses of wine per week.
Even those who have 10 drinks a week could be shortening their lives by up to six months. What scientists found is that drinking can significantly increase the risk of cardiovascular illness. Every 12.5 units of alcohol raises the risk of stroke by 14%, fatal hypertensive disease by 24%, fatal aortic aneurysm by 15% and heart failure by 9%.
Also, drinking alcohol has been linked to a reduced risk of non-fatal heart diseases.
You might have heard about previous studies stating that drinking red wine can be good for your heart. However, the fact that some scientists have suggested that drinking wine is good for you is a little bit overhyped.
Dr. Angela Wood, a lead author of the study, from the University of Cambridge, said: “The key message of this research is that, if you already drink alcohol, drinking less may help you live longer and lower your risk of several cardiovascular conditions.”
Being Overweight Can Damage Your Liver
Not only is drinking bad for your liver, but being overweight can make things worse as well. Scientists are saying that the situation is getting very alarming when it comes to being overweight. Being overweight can lead to liver failure or even death. This is especially alarming since symptoms don’t often emerge until permanent damage is done, however, the condition can be reversible if caught in time.
Frances who struggled with being overweight said for BBC: “I was shocked when I was told my liver was diseased but determined to do something about it. I started by eating more healthily and then combined that with physical activity – I’m delighted my liver is back to normal.”
There are too many findings that being overweight could be as bad as smoking when it comes to health risks. Stay physically active and eating healthy is something that we should all do no matter how much time we have in our busy schedules.
Taking care of yourself should be the number one priority when we are dealing with being overweight.
