Evidence suggests depression shortens human life. If you want your children to live as long as possible, it may be best to take away their iPhone.
The arrival of the smartphone has radically changed every aspect of teenagers’ lives, from the nature of their social interactions to their mental health. These changes have affected young people in every corner of the nation and in every type of household. The trends appear among teens poor and rich; of every ethnic background; in cities, suburbs, and small towns. Where there are cell towers, there are teens living their lives on their smartphone.
All that time on the phone breeds loneliness and depression.
When is your child not staring at a screen?
We used to believe that marriage led to longer lives, especially for men. New research suggests this may not be true — or at least, not true any longer.
“The protective effects of marriage have eroded over time,” which is consistent with several other recent studies that cast doubt on common wisdom that marriage has health-promoting effects.
The only married people who turned out to be healthier than their non-married counterparts were women who had been married for ten years or more — and that was only true for the oldest cohort in the study (those born between 1955 and 1964). For younger women, that protective effect did not exist.
Reminder: your health — and longevity — is your responsibility. Even a loving partner may not be enough to maximize your lifespan. Take action, daily.
Unlike marriage, calorie restriction almost certainly leads to longer life. For most, however, this is very difficult, particularly in western societies where movement is discouraged and garbage food is plentiful.
This study suggests that periodic fasting may work just as well and should be much easier to do.
(Valter) Longo (PhD) placed middle-aged mice on a periodic fasting schedule in which, twice a month, the mice were placed on a restricted diet for four days. Their diet was relatively high in fats while being restricted in proteins and sugars. So, for eight days a month, they were on a low-calorie, low-protein/low-sugar diet.
The remainder of the time, they ate normally. When the volume of food was averaged out over the month, they were actually not calorie restricted at all, as they made up for the temporary restriction by eating slightly more afterward. Still, these mice had half the tumors of the control group, which had no fasting period. Even when tumors did develop in the treatment group, they developed later and were mostly benign.
That’s an amazing result.
It also nudges us toward acceptance of a high-fat diet for life extension.
Probably, it won’t help you — these innovations are simply taking too long to bring to us — but editing of human embryos reveals amazing potential for radical life extension. The many philosophical concerns and unplannable realities, notwithstanding.
Scientists have, for the first time, successfully freed embryos of a piece of faulty DNA that causes deadly heart disease to run in families.
It potentially opens the door to preventing 10,000 disorders that are passed down the generations.
The US and South Korean team allowed the embryos to develop for five days before stopping the experiment.
The teams focused on “hypertrophic cardiomyopathy. The disorder is common, affecting one in every 500 people, and can lead to the heart suddenly stopping beating. It is caused by an error in a single gene (an instruction in the DNA), and anyone carrying it has a 50-50 chance of passing it on to their children.”
