Having more children could slow aging

In the journal PLOS One, researchers reveal that women who had more children had longer telomeres than women who had fewer children.

Telomeres are caps at the end of each DNA strand that protect our chromosomes - thread-like structures that contain all our genetic information - from damage.

Each time a cell replicates, telomeres become shorter. They eventually become so short that they stop protecting chromosomes, leaving them vulnerable to damage, which in turn causes our cells to age and stop functioning effectively.

Previously, animal studies have supported the "life history theory," suggesting that higher reproductive behavior is associated with accelerated biological aging.

However, this latest study, led by Prof. Pablo Nepomnaschy and Cindy Barha - both of Simon Fraser University in Canada - contradicts this theory.

    Hello there! I know this is kinda off topic but I was wondering which blog platform are you using
    for this site? I'm getting sick and tired of Wordpress because I've
    had problems with hackers and I'm looking at options
    for another platform. I would be fantastic if you could
    point me in the direction of a good platform.

    JAKARTA, June 22 (Reuters) - Indonesia has changed where it will host ASEAN's first-ever joint military exercise
    to a location away from the South China Sea where several countries
    including China have overlapping territorial claims,
    its military said on Thursday.

    The non-combat drills for members of the Association of Southeast Asian Nations (ASEAN) were originally set to
    take place in the southernmost waters of the
    South China Sea, which are also claimed by Beijing.


    But the September 18-25 exercise will now be moved out
    of the strategic waterway altogether to the South Natuna Sea in Indonesian waters, said military spokesperson Julius Widjojono.


    "This exercise is focused not on combat, so it is best suited for the south that is in direct contact with the people," he said,
    adding the drills will be held in and around Batam island at the mouth of the Malacca Strait.


    ASEAN's unity has for years been tested by a rivalry between the United States and China that is being played out in the South China Sea, a conduit for about $3.5
    trillion of annual ship-borne trade.

    Vietnam, the Philippines, Brunei and Malaysia have competing claims with Beijing, which asserts sovereignty over
    vast stretches of ocean that include parts of Indonesia's
    exclusive economic zone.

    China claims sovereignty over the area via an expansive
    'nine-dash line' based on its historic maps, which an international arbitration court in 2016 ruled had no legal basis.


    ASEAN has been pushing to complete a long-awaited maritime code of conduct with China,
    and several of its members have had run-ins with Beijing in recent months.



    The military of Indonesia, which chairs ASEAN this year, said the
    decision to move the location was an independent
    one and that there was "no intervention" from other countries.


    It also said Cambodia and Myanmar did not respond to an invitation to a preparation meeting for the exercise held on Monday
    among ASEAN countries.

    Both Myanmar's junta leaders and Cambodia have close
    ties with China. (Reporting by Stanley Widianto; Editing by Kanupriya
