TEXTO:

     Since the early 21st century, numerous studies
have shown how aerobic exercise promotes the
generation of new brain cells and white matter
integrity in people who exercise regularly. However,
[5] there’s still a lot of uncertainty about the exact “doseresponse” related to how much time people should
spend being physically active in their daily lives. And
nobody is certain about what intensity (easy, moderate,
vigorous, or intense) of physical exercise is ideal
[10] for optimizing brain structure and functional connectivity
across a lifespan.

    A recent study, conducted by researchers in
California and in Japan, shows that a single 10-minute
bout of very light physical activity can increase the
[15] connectivity between brain regions linked to memory
formation and storage. What makes this study unique
is that the researchers have demonstrated a more
immediate impact related to the strengthening of
communication lines between memory-focused parts
[20] of the brain after a single 10-minute bout of light activity
that wasn’t aerobic. 

     For this study, the researchers recruited 36 healthy
young adults and had them perform 10 minutes of very
easy physical movements such as tai chi or gentle yoga.
[25] Immediately after the brief session of physical
movement was completed, each person’s brain was
scanned using high-resolution functional magnetic
resonance imaging (fMRI). In comparison to a control
group that hadn’t done any physical activity, those who
[30] had gently moved their bodies for 10 minutes prior to
the brain scan showed better connectivity between the
hippocampal dentate gyrus as well as cortical areas
linked to detailed memory processing and storage. “The
hippocampus is critical for the creation of

      new memories; it’s one of the first regions of the brain
to deteriorate as we get older — and much more
severely in Alzheimer’s disease,”they said.

Medical information on the web has pros and cons

By Christian Vey

Jan 2, 2012

You feel a twinge in your stomach and there is no
obvious explanation. Or maybe, for no apparent
reason, you get a stabbing headache. To whom - or to
what - do you turn first? According to various studies,
there is a good chance it is the internet.

'About 65 per cent of respondents now state that they
have recently searched for health content on the
internet,' said Marie-Luise Dierks, co-director of the
Hanover Patients' University, an independent
education institution at Hanover Medical School in
Germany. Some, though by no means all of them, try
to diagnose themselves.

Independently researching a health-related matter on
the internet can indeed be useful, said Dierks, who
said it is a good way to boost one's self-reliance and
confidence in dealing with illnesses, doctors and
medicine. But she added a caveat: 'It's important,
however, that information from the web always be
called into question.'

Health care professionals are divided on the internet
as a source of medical information. 

'There is nothing wrong with informing oneself,' said
Ursula Marschall, medical director of a German public
health insurance company. But she said it is
dangerous to regard the internet as more credible than
one's doctor. Noting that 'patients always have their
own notions about their illness,' she said those who
did internet research were at risk of latching onto
information that supports their preconceptions, even if
these latter ones are completely wrong.

Maria Gropalis, a psychologist at Mainz University's
Department of Psychology, also sees risks. 'The
danger of misinformation is very high on the internet.
The overabundance of information can be a problem
as well' - particularly for hypochondriacs, she said.
'There's the risk that the internet will intensify existing
fears.'

A word has even been coined for unfounded anxiety
concerning the state of one's health brought on by
visiting medical websites: 'cyberchondria.' While
Gropalis views the neologism as mainly a vogue word,
she said the phenomenon it described was definitely a
modern variety of hypochondria.

TEXT

I am tired of assimilating things to other things,

I hardly see things as they are, as it is.

The Jasmine flower _______ my garden too, is tired,

someone said she looked like a cotton field.

So, she stretched her limbs, tearing her fibers.

I used to compare death,

to a dreaded darkness we lost our keys in,

to a dream we can't awake _______,

to the hollow _______ an idol we debase ourselves to...

Until the day my father

hit the floor and died.

Then, death became death,

just death.

I am innocent of similes.

I compared myself _______ an ear of wheat and got trapped in it,

Darwin has since been staring at his table.

I am innocent of poetry. 

These are just lullabies | write to help me sleep.

These are just spells | write and fold,

to help me write again.
