The DNA molecules undergo chemical changes during our lives
 
By Hector Reyna
 
An expert in Molecular Medicine, from the Karolinska Institute, Juleen Zierath, concluded that epigenetic changes are usually given by physical exercise. Such modifications could clarify the fact that sport is so productive for the body.
 
Zierath studies have revealed that the DNA of skeletal muscle taken from a person after intense exercise practiced involves less methyl groups attached to their molecules before exercising.
 
Zierath says in his study: these changes occur in stretches of DNA that normally act on enzymes called transcription factors, compared with "keys" that unlock the muscle genes. These keys work best when there is no methyl groups in between that prevent the passage. DNA changes caused exercise increases the muscle's ability to work.
 
In addition, exercise improves and accelerates the metabolism of fats and sugars.

More than two of the 11.2 million people in Cuba are older than 60 years and approximately 551 thousand people are over 100 years old.
 
Luisa Bathilde Lima, a researcher who between 2008 and 2010 examined 80 centenarians living in areas of eastern Cuba could see that the country ranks second worldwide in the number of centenarians per capita exceeded only by the region of Sardinia in Italy. Lima concludes from her study that being obese or overweight is bad for longevity.
 
The researcher concluded from her study that interviewed people with more than 100 years in the eastern region of Cuba shared the unique characteristics: Drinking coffee and being thin people. According to Lima, people reported eating a little and in several portions during the day with an established feeding schedule and a unique preference for milk.
 
Most subjects were peasants, very active and of good character, demonstrating to have been good people over the course of their lives. The "head" of the Cuban centenarians is Juana de la Candelaria Rodriguez, who is 126 years and still, lives in the eastern province of Granma.
 
Life expectancy at birth in this country is 78 years on average, 76 for men and 80 for women; which exceeded by 20% to men within the community of centenarians in Cuba.
