Eating more vegetables can cure Alzheimer
American scientists conducted a research for almost 5 years with 560 volunteers at the average age of 81,
which collected the information about these people’ diets including spinach, kale and lettuce. Once a year, they had to take tests about intellect and memory.
The result showed that all of the paripants in the research did not suffer from Alzheimer. The collected information would provide more surprising evidence about the link between diets and aging, in which the groups eating more vegetables were about 11 year old younger on the average than those who did not
Intellect and memory tests showed that people who ate less than a portion of vegetables every day had the rate of memory loss more slowly than those who ate very little or hardly ate

Lời Anh:
Worst Day Ever?
Today was the absolute worst day ever
And don’t try to convince me that
There’s something good in every day
Because, when you take a closer look,
This world is a pretty evil place.
Even if
Some goodness does shine through once in a while
Satisfaction and happiness don’t last.
And it’s not true that
It’s all in the mind and heart
Because
True happiness can be obtained
Only if one’s surroundings are good
It’s not true that good exists
I’m sure you can agree that
The reality
Creates
My attitude
It’s all beyond my control
And you’ll never in a million years hear me say that
Today was a good day
Now read from the bottom to top.

Russian President Vladimir Putin signed a decree to suspend INF
Reuters reported on March 4 that the Kremlin announced that Russian President Vladimir Putin had signed a decree to suspend Russia's paripation in the Mid-Range Nuclear Force (INF) Treaty with the United States.
President Putin has ordered this treaty to be suspended until Washington stops the violation of INF. Putin also directed the Russian Foreign Ministry to inform the US of Moscow's decision.
In February, Russia said it would suspend the treaty after the US announced it would withdraw from INF, citing Moscow's breach of the treaty.
However, Russia rejected this allegation and accused Washington of breaking the INF.
